POSSIBILITIES OF COMBINED METAL HARDENING WITH WAVE DEFORMATION AND SUBSEQUENT HEAT TREATMENT

Nowadays, industry development requires making new strengthening technologies that allow expanding the rational scope of their application. It is quite promising to use methods combined hardening changing physical and mechanical properties surface layer during successive external actions having different nature: sequential plastic deformation thermal effects. Therefore, objective conducted study make a complex technology hardening. Preliminary proposed be carried out by method wave hardening, in which improvement achieved forming structural imperfections crystal lattice material under action prolonged shock pulses significant energy duration. The these contributes more complete hardened metal formation deeper than with traditional technology, consisting before treatment, allows obtain high hardness plasticity layer, provides an additional resource increase operational characteristics part. novelty work for alloy steels. studies have shown efficiency various grades
