| Annotation |
Investigations are given of the influence of thermal, thermochemical treatment of die steels on the development of
thermomechanical fatigue cracks depending on the temperature-force effects characteristic of hot deformation dies. As
the evaluation criteria for the thermomechanical fatigue resistance of surface hardened die steels, the moment of
nucleation, their quantity, and the depth of propagation were used. The study of the laws of the development of
thermomechanical fatigue cracks in die steels in copper melts is carried out in an analogous manner, which provides a
similarity to the operational loading of the material according to the local stress-strain state and the conditions of
interaction with the molten melt. Dependences of the depth and number of cracks formed in 4X4VMFS DI22 die steel,
hardened by various methods, on the number of loading cycles are established. It has been established that the
performance of a stamping tool in a variant with diffusion hardening is determined by the specific laws of softening and
destruction of contact zones. Moreover, the occurrence of cracks in the initial stages of operation is not decisive. The
positive effect of boriding and nitriding on the performance of the dies is associated with increased structural stability of
the diffusion saturation zones, which ensures the maintenance of a high level of mechanical characteristics of the tool
working surfaces - hardness, strength, and as a result of high wear resistance. The analysis of the results of studies of the
patterns of crack formation in steel 4X4VMFS DI22, subjected to various hardening methods, indicates the promising
use of nitriding and boriding to increase the life of dies. |
