ABSTRACT:
Wear-resistant and shock-resistant tools are constructed by preforming carbide-containing working parts of high wear resistance and hardness and attaching them to a softer base metal of the tool by means of a highly shock-resistant steel-to-steel fusion weld. The working part is preformed by powdered metallurgy techniques utilizing steel powders having carbide-forming constituents therein which form carbides along the grain boundaries of the steel uniformly throughout the working part as a result of sintering of the compressed powders. Thereafter the fusion welding process renders the carbide structure of the working part nonuniform for optimum shock resistance, without reducing the effective wear resistance thereof, while also forming a highly shock-resistance joint between the working part and the base metal of the tool.
