Influence of Cutting Conditions and Radius of the Rounding of Tool Made of Composite 10n on Surface Layer State During Turning of Hardened Steels

The results of studies of the type influence of treatment and tool material on the structural state of the boundary layer 107WCR5 during treatment are shown. The advantages of turning chisels with composite 10 compared with the process of grinding. Processing treatment with composite 10 in the surface layer for α-and γ-phase is accompanied by compressive residual stresses only, while the abrasive treatment is accompanied by tensile stresses in the kind of I-α- phase structure of high-speed dispensing.

Reconstruction of the tectonic stress field before and after Japan earthquake 11 march 2011

Purpose. The purpose of the research is to study the features of the tectonic stress field before and after the 2011 Japan earthquake. Methodology. The reconstruction of the tectonic stress field is carried out on the basis of cataclastic analysis method of earthquake focal mechanism. The method allows us to define the tectonic stress tensor parameters and increments of quasi-plastic deformation. Results.
