Conclusions
Thus, the theory considered above permits a unified description of the behavior of pure metals and certain classes of alloys in the transition stage from elastic to homogeneous macroplastic deformation. Tt accurately reflects the law of accumulation of plastic deformation up to the physical yield point and the form of the extension curve above the yield point. Its predictions as to the dependence on grain size of the macroscopic elastic limit, upper and lower creep limits, value of the “tooth,” and extent of the creep area correspond to experimental data.
