METALLOGRAPHIC STUDY OF THE DEFORMATION OF A PARTICLE STRENGTHENED ALLOY, WC -Co. Technical Report No. 1

Technical Report ·
OSTI ID:4315835
A metallographic investigation of the deformation in bending of a number of tungsten carbide --cobalt alloy compositions was carried out as part of a study of the mechanical behavior of aggregates of ductile and brittle constituents. It was found that the ductile failure of the cobalt-rich alloys is preceded by localized plastic flow of the matrix and by cracking of the carbide grains. The carbide-rich compositions faiIed in a brittle manner by cathatrophic propagation of cracks through the carbide grains. (auth)
