Cracking resistance and strength of carbide steels

Carbide (WC) steels with binders of austenitic Cr-Ni (TKhN) or austenitic-martensite nickel (TNS-A) steels are shown to have a cracking resistance which is comparable to that of the tungsten carbide hard alloy (WC-Co). A relationship was established between the cracking resistance and certain proper...

Description
Summary:Carbide (WC) steels with binders of austenitic Cr-Ni (TKhN) or austenitic-martensite nickel (TNS-A) steels are shown to have a cracking resistance which is comparable to that of the tungsten carbide hard alloy (WC-Co). A relationship was established between the cracking resistance and certain properties of the carbide steels: a reduction in hardness and proof stress, and an increase in the limiting plastic strain in compression, give rise to an increase in K sub 1c .
