Determination of power influences in the processing of metals by pressure. Tutorial. Brovman T.V.

The results of the study of the energy -sedenary parameters of the processes of rolling, pressing, and dragging are given, the characteristics of a number of metals that showed anisotropy during deformation are given. Decisions were obtained on the flow of metal in a converging channel, flat plastic deformation of the anisotropic medium when compressing the workpiece between hard plates. The coefficients of a stress state for functions that describe the anisotropy of the limitability anisotics are given. Calculations were made and graphs of the coefficients characterizing the effect of anisotropy on increased deformation were built. Formulas showing the connection of the limits of fluidity with flat deformation and single -axle stretching are displayed. Formulas are proposed that take into account the joint influence of the degree of deformation and deformation rate. The law of voltage removal during recrystallization has been investigated, which will allow to move on empirical dependencies for resistance to deformation to the formulas derived based on the real physical processes occurring in the metal.
