摘要：
The coagulation of the cementite in steel after preliminary cold deformation and during deformation at subcritical temperatures has been studied. The degree of coagulation was evaluated in terms of the change in the number of particles and the microhardness. After preliminary cold deformation and during deformation at subcritical temperatures the greater the deformation and the higher the deformation rate the more coagulation is accelerated. Interrupted deformation at subcritical temperatures is more effective than continuous deformation. The effect of deformation on the coagulation of cementite is associated with increased crystal structure defect density in the ferrite close to cementite particles.
