摘要

In the present study, values of yield strength of individual layers of layered composites based on different strength mild steels obtained by explosion welding followed by cold rolling and heat treatment were determined. The effect of cold rolling with a total reduction of 50% and heat treatment at a temperature of 500 degrees C on the change of the deformational resistance of Fe-2Mn-Si and Fe-11Cr-9Ni-2Mo-1Ti steels' layers in the composite was established. It was shown that additional cold deformation of the layered composite leads to an increase in yield strength of Fe-2Mn-Si and Fe-11Cr-9Ni-2Mo-1Ti steels' layers by 20% and 24%, respectively, and additional heat treatment of the cold-deformed composite contributes to strengthening of the Fe-11Cr-9Ni-2Mo-1Ti steel layers by 17% and softening of the Fe-2Mn-Si steel layers by 6%. It was shown that the level of strengthening of the Fe-11Cr-9Ni-2Mo-1Ti steel layers after cold rolling corresponds to the level of strengthening of this steel after heat treatment. It was determined that the maraging steel layers with initial ultrafine-grained microstructure are intensely strengthened (35%) by conducting combined heat-deformational processing of a layered composite, including cold rolling with a total reduction of 50% and subsequent heat treatment at a temperature of 500 degrees C.
