Cast Iron,iate steels were developed. It is relatively cheap, is readily castable, easy to machine and its moderate tensile strength combined with high compressive strength make it suitable for applications requiring rigidity and wear resistance. For these reasons it is used in numerous structural and machine

High Temperature Composite Materials,ity of the existing systems rather than to increase the temperature capability. Historically high performance composite materials have been developed primarily to meet the aerospace industry need for strong, lightweight structures of high stiffness. The glass fibres, which were available as reinforc

Coatings for High Temperature Materials,formance requires the component to have resistance to these environments as discussed earlier. In some applications the inherent resistance of the base material must be supplemented by a coating in order to ensure the required component life.
