## Abstract The mechanical behavior of the Ti‐6Al‐4V ELI alloy in both conventional grain size (CG) and ultrafine‐grained (UFG) conditions under tension and compression at elevated temperatures (500–800 °C) is considered. Grain refinement by equal‐channel angular pressing (ECAP) followed by multicy
A high temperature split Hopkinson pressure bar (SHPB) test system is used to investigate the effects of temperature as well as those of strain and strain-rate. Effects of temperature for the titanium alloy (Ti-6Al-4V) are investigated by developing a high temperature SHPB test system. In this work,
Ahatraet-The cyclic stress-strain behavior and the SIN behavior of a "pseudo-elastic" alloy, Ti-6AL-4V of coarsened micros~uct~ and of a "plastic" material, copper, are compared. In accord with views recently put forth by Freudenthal, important differences are noted between these two types of materi
