The paper is dedicated to memory of Prof. Silvana Lux of Johannesburg (South African Republic), a prominent researcher in the field of powder metallurgy and hard alloys, whose talent and managerial abilities have made possible joint investigations of researchers from Ukraine and SAR.

Abstract

The publications reporting systematic investigations of the effect of structural state of WC-Co hard alloys (the cobalt binder content, WC grains size and contiguity) and temperature on mechanical properties and deformation mechanisms have been reviewed and generalized. The ductile-brittle transition, strain hardening, special features of WC-Co alloys deformations in various temperature ranges, and specificity of mechanical properties of the alloys with submicron WC grains have been discussed.
