Description
The effect of mechanical deformation scheme on mechanical properties and structure of fine-crystalline superplastic materials, is investigated. The effect of deformation mechanical scheme on the flow stress and integral value of optimum deformation rates in the case of superplastic flow of Ln+22% and VT9 alloys, is established. At low and high deformation rates, flow stresses for upsetting and tension are equal. In the range of optimum deformation rates for sagging, flow stresses during tension is somewhat higher than during upsetting. For deformation schemes characterized by the presence of positive hydrostatic pressure (primary effect of compression stresses); in the range of optimum deformation rates, the increase in grain growth of phases in Ln+22% and VT9 alloys is observed as compared with deformation by tension
