抄録

Microscopic studies to obtain correct informations on the mechanism of brittle fracture process of cermets (WC-Co-cemented carbides and TiC-base alloys) were carried out. The preferential cracking of carbide grains in these cermets at low temperature, the effect of strain rate on the carbide cracking, origination of the initial cracks, their progressive growth to fracture, dangerous length of the fracture to break down the specimen and the discrepancy between the mode of fracture at low and at high temperature, etc. were described. The flake graphite precipitate and the chrome carbide aggregates in TiC-base cermets were noticed as possibly dedrimental to their mechanical properties.
