摘要：
We investigate the kinetics of damage of the material of hard-alloy (tungsten carbide-cobalt) teeth of drill bits under cyclic compressive load. Three stages of damage of the structure up to the critical fracture of a tooth are found. The dependences of the relative duration of each stage on the amplitude of the applied loading and on the alloy composition are established.
