Abstract:

It is proposed that major development efforts on ultrahigh carbon steels UHCS and their laminates are timely and programs to evaluate prototype structural components should be initiated. The hardenability of fine grained UHC steel is improved by dilute alloying additions of manganese, aluminum and nickel. The impact resistance of UHCS laminated composites, after selective heat treatment, can be enhanced by appropriate choice of interleaf material. Two factors are important the interlayer boundary should be discrete and the interleaf material should be notch ductile. Several interleaf materials have been investigated including Fe-3Si, Hadfield manganese steel, 304 stainless steel, Fe-9Ni-2Si and brass. aw
