Hardening Process by Complex Local Deformation Investigation

Abstract

The article considers a new method of sliding bearings inner surface hardening by plastic deformation in complex local loading of deformation zone conditions. The main aspects of experimental equipment construction and experimental research preparation are reviewed. The laboratory research results are presented.

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

“…Obtained results of microhardness parameter mesuring correlates with researches [32][33][34][35] carryed out earlyer, that allows to predetermine about 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 microstructure and mechanical parameters -microhardness parameter value in dependence of accumulated degree in particular becomes possible.…”

“…At the same time stabilization of HV value at radial out of center direction, that correlates to crack size and quantity minimisation. This character of controlled parameters changing allows to predetermine about intensive plastic deformation beginning, that, as noticed in works [32][33][34][35], facilitates to material mechanical and expluatation parameters combination optimisation. Also it's necessary to pay attention to aspect that researches carryed out allows to realize: 1.…”

“…At present time a lot of methods of hardening processing are exists [1][2][3][4][5]. They can be subdevided on 6 groups (Fig.…”

“…For theoretical investigation of the studied processes [26][27][28][29][30][31] the decision of application package "STAMP", developed by authors team of Orel State University named after I.S. Turgenev with state-of-the-art of processing of metals by pressure and mechanics of rigid body, usage has been made.…”
