The simulation of hot forming operations by means of torsion testing has been performed on Udimet 700, a nickel base alloy. The purpose of this research was threefold: 1) to evaluate the hot working (T >.7 Tm) properties of the U -700 alloy, (tests were conducted as low as.45 Tm), 2) to attempt to simulate the extrusion of this alloy by means of torsion testing under comparable conditions of temperature, strain rate and strain, and 3) to evaluate the torsion test as a laboratory technique for developing hot worked microstructures under controlled conditions of temperature, strain, and strain rate. |
