Composite Materials

...composite materials are strongly dependent on micro structural parameters of the system. The evolution of microstructure depends largely on the cooling rate during phase change. Though the microstructure evolution depends on many process parameters, the final structure is decided by cooling conditions during solidifications. The mould material has a decided effect on the structure formation. The use of end chills during casting not only favours directional solidification but also accelrates solidification. Faster cooling rates give rise to finer structures and improved mechanical properties. In this work an attempt is made to prepare Al-B4C composites cast using stainless steel and cast iron chills in a colplete adiabatic system. The microstrucutre and micro-hardness of the chill cast specimens are analyzed and reported. It is observed that the chill material has a significant influence on the microstructure and properties of the cast specimens. Finner structure and better mechanical properties were observed with the specimen cast using stainless-steel chill whereas cast iron chill gave rise to coarse structure with reduces mechanical properties. INTRODUCTION Engineering Materials There are more than 50,000 materials available to engineers for the design and manufacturing of products for various applications. These materials range from copper, cast iron, brass, which have been available for so many years, to the more recently developed advanced materials such as......

...what happens in USA, corrosion of metals costs the economy almost $300 billion per year at current prices, which translates to 3-4% of GDP. Besides the economic concern, corrosion may adversely affect the environment. Worse than all those mentioned, corrosion can cause unexpected death from corrosion-related accidents. For example, the sudden collapse caused by corrosion fatigue of the Silver Bridge over the Ohio River in 1967 cost 46 lives on top of the needless-to-say millions of dollars material loss. Therefore, the benefits brought about by corrosion are outweighed by its detriments. The fact is, about 33% of these costs could be diminished by using corrosion-resistant materials. Being defined as the sideways displacement of material from its original position on a solid surface performed by the action of another surface, wear is another mechanical property of materials that materials scientists consider when selecting materials in a design task. In order to be wear-resistant, a material must be hard and strong. The demand for corrosion- and wear- resistant coatings is nowadays rapidly increasing, especially in oil and gas industries. The most common solutions are Hard Cr and Quench-Polish-Quench (QPQ) processes. However, these two processes affect the environment adversely. As alternatives, coating layers can be introduced to metal samples. Coatings can be done with or without electricity. If electricity is involved, the process is called electroplating. It is done by......

Material Handling

...How to solve the limitations of the current system. Material handling equipment is about roles in moving, storage, and control of the goods. The categories of material handling are traditional and modern. 1. Traditional (i) Used human power (ii) Not value adding (iii) Minimize used of since it depend on the capabilities of the human to handle the risk 2. Modern (i) Used robotic system/ computerise system (ii) Adding value (iii) Maximize flexibility of used Detection systems and RFID-based automated material handling is now available and common to many of these industries are particularly flatbed conveyor. MHS based flatbed conveyor systems bring themselves to control complexity, additional storage equipment such as baskets and trays and additional user activity. The meat processing industry in the UK has refused to adopt the system because of the cost of installation if there is no commercial benefit in a financial decline through food fear accompanied by potential incompatibility between the issues of system reliability and the imposition of additional stress operator. Based on time constraints, the research has been conducted on the MHS can solve the limitations of the current system. Therefore, a consortium project called Meatract, was established to research and develop novel MHS automatically detect and track cuts in the......

Accounting for Materials

...ACCOUNTING FOR MATERIALS – MATERIALS Definition Materials: | In cost accounting material is defined as the part of inventory. Basically, material and raw material are used for same purpose. This is main part of total cost of production. It can reduce or increase according to the fluctuation in production. So, this is very flexible and controllable source of production. For making furniture, wood is the material. 60% to 70% proportion in the total cost of production will be material cost.  So, it is very necessary for producing any new product. Its cost will reflect the profit of company directly. This input can be stored and transported from one place to another. Material control is a systematic control over the purchasing storing and using of material to minimizing the possible cost. In every manufacturing concern materials constitute an important factor of production. It is an important element of cost & covering 60-70 percent of the total cost of the production. Material control may be defined as the level of material maintenance so as to ensure uninterrupted production and minimizing the investment of funds. Thus material control is the proper control of material which reduces the cost of production, minimizing the investment of fund in the purchases of material & increases the profitability of the organization. Material control is the system that ensures the provision of the required quantity of material of the required quality at the required time......

Montessori Material

...Maria Montessori described the sensorial material as the key to the universe discuss this statement and give examples to support your discussion. Dr,Maria Montessori was dedicating herself to understanding how and why children learn. Montessori discovered that the child learns different from an adult, the child seeks an internal aim but the adult seeks external aim. Maria believed that the first years of the child is the most important one; the child is forming his personality and absorbing every thing from the environment. She called this period from 0-3 the unconscious mind. And the second period is called the conscious mind is the age from 3 - 6 years the child now is building his will and his memory. "The tiny child's absorbent mind finds all its nutriment in its surrounding especially at the beginning of life .we must there- fore, make the environment as interesting and attractive as we can." ( The Absorbent mind ). The child also needs freedom in order to develop. A prepared environment is a place that is created for a special purpose. In this to assist the full and natural development of children between ages of 3-6. The prepared environment should contain everything that is necessary to enable the child 3-6 to develop fully. To achieve this it must also make it possible for the child to function independently, to explore and discover for himself. It should also be attractive so that invites the child and every thing should be accessible to reach. Dr......

Material Deprivatoon

...Outline some of the ways in which material deprivation may affect education achievement. (12 marks) Material deprivation is the poverty and lack of material necessities, such as adequate housing and income. As an example, only 33% of children receving free school meals gained 5 or more GCSEs at A* - C in 2006, as against 61% of pupils not receiving free school meals. A factor of material deprivation affecting children’s education would be poor housing. This can affect pupil's achievement both directly and indirectly. It can be directly affected by overcrowding for an example, meaning less room for educational activities, nowhere to do homework or lack of sleep from sharing a room. An indirect example would be a child's health and welfare. Children in crowded homes run a greater risk of accidents. Cold or damp housing can also cause ill health. These problems mean more absences from school. Another factor would be a pupil's diet and health. Children from poorer homes are more likely to have emotional or behavioral problems. Richard Wilkinson research showed that among 10 year olds, the lower the social class the higher the rate of hyperactivity, anxiety and conduct disorders, which are all likely to have a negative effect on the child's education. Marilyn Howard noted that young people from poorer homes have lower intakes of energy, vitamins and minerals. This would also lead to more absences from school due to illnesses as well as difficulties with concentration in......

Material

...2 Materials BASIC CONCEPTS AND FORMULAE 1. Maximum Level: It indicates the maximum figure of inventory quantity held in stock at any time. 2. Minimum Level: It indicates the lowest figure of inventory balance, which must be maintained in hand at all times, so that there is no stoppage of production due to non-availability of inventory. 3. Re-order level: This level lies between minimum and the maximum levels in such a way that before the material ordered is received into the stores, there is sufficient quantity on hand to cover both normal and abnormal consumption situations. 4. Danger level: It is the level at which normal issues of the raw material inventory are stopped and emergency issues are only made. 5. ABC Analysis: It is a system of inventory control. It exercises discriminating control over different items of stores classified on the basis of the investment involved. Items are classified into the following categories: A Category: Quantity less than 10 % but value more than 70 % B Category; Quantity less than 20 % but value about 20 % C Category: Quantity about 70 % but value less than 10% 6. Two bin system: Under this system each bin is divided into two parts - one, smaller part, should stock the quantity equal to the minimum stock or even the re-ordering level, and the other to keep the remaining quantity. Issues are made out of the larger part; but as soon as it becomes necessary to use quantity out of the smaller......

Indigenous Materials

... TECHNOLOGY  1     H  13.0  –  INDIGENOUS  MATERIALS   INDIGENOUS: Originating and living or occurring naturally in an area or environment; natural or in-born. Indigenous materials are generally considered to be materials which are produced in the same bioregion or regional ecosystem where they will be used, although some practitioners consider materials to be indigenous only if they are available on the same site where they will be used. Bamboo, Clay, Coconut, Cogon Grass, Lime, Rattan Bamboo is from the grass family and is one of the fastest growing plants on earth, however it is susceptible to fungi and insect attacks. Bamboos are among the plants most widely used by humans. In the tropics they are used for constructing houses, rafts, bridges, and scaffolding. Split and flattened culms can be used as flooring and interwoven to make baskets, mats, hats, fish traps, and other articles; culms of large species may be used as containers for liquids. Laminated Bamboo Lumber is made of high quality bamboo. It is laminated with LFM Resin with high bonding strength and non-toxic to human.It is used for bamboo furniture and art and craft products. Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Optimum growth is with a mean annual temperature of 27°C, and growth is reduced below 21°C.
