DID YOU KNOW:
ENGINEERING MATERIALS
Materials are one of the main input
elements in a production process. The process converts the raw materials into
useful products. You will notice that nowadays many products ranging from
automobile parts and electrical appliances to medical application are made from
plastics, composites and other polymers. The commonly used metals, however,
will still be used for load-bearing and heat-resistant structures.
Materials that can be used to manufacture a product
have such diverse properties that even when we consider the performance and
cost, it is still difficult to decide what material to use for a particular application.
One material may have higher strength but poor corrosion resistance. Another
material may have high strength and good corrosion resistance but difficult or
expensive to be processed into the finished product. It is important for us to
understand their properties, reliability and manufacturability before we
can effectively and efficiently use them in making new products
