The recent advances of research of wear resistant steel including austenitic manganese steel, low alloy martensitic steel and bainitic steel are summarized in this paper.

Structural steels, Carbon content. Low-alloy steels. Ferritic and martensitic stainless steels.

Shape memory effect of alloy is obtained by making use of martensitic phase transformation induced by stress or temperature. Shape memory alloy is a new kind of function materials.
