Analog investigation of thermomechanical fatigue surface - hardened steels used for making the press -forms of pressure casting of aluminum alloys
The origin and development of cracks thermomechanical fatigue (TFC) in die steels 3H2V8F, 4H4VMFS 4H3VMF after nitriding, cyanidation, Boriding, EDM surface alloying and surface claddings for various loading conditions of the samples in experimentation, the parameters corresponding to the cyclic temperature-force loading press-forms of casting aluminum alloy were investigated by analog patterns.
