Abstract:

The purpose of this report was to explain the possibility of obtaining stable properties of goods from the VT14 alloy, prepared under conditions of series manufacture by thermomechanical processing. The use of thermomechanical processing with hot stamping improves the mechanical properties of the VT14 alloy, above all its plasticity. It raises the stability of the elongation factors, narrowing and impact viscosity. The increased plasticity of the VT14 alloy after thermomechanical processing appears to be the result of a greater dispersion of structural components, causing a greater number of possible sliding planes and doubling and a more uniform distribution of the same over the entire metal in the process of deformation or elongation. When evaluating the advisability of using thermomechanical processing, it is necessary to consider the reduced hardening of the VT14 alloy. In simple form details, when a high deformation degree is fulfilled, at a low temperature, the high properties can be assured at an ordinary stamping technology. Author
