Evolution of BrOCS 5-5-5 Alloy Microstructure and Mechanical Parameters under Intensive Plastic Deformation Conditions

Abstract

The complex approach to the microstructure and microhardness parameter of BrOCS 5-5-5 changing dependences out of hardening degree are presented. The acquired results correlate with the earlier research, but give us new knowledge about the microstructure and microhardness parameter value changes depending of the deformation degree. That allows predetermining the accumulated deformation degree at bush type hardening process, for example – plain bearing liners or structural elements in the form of axial symmetry tybes. The prediction of the microstructure and mechanical parameters – microhardness parameter value in dependence of accumulated degree in particular becomes possible. The microstructure research carried out allows predetermining the necessary deformation degree for the studied material for its further application.
