Abstract

The compression behavior of two commercial polycrystalline Ti-Al intermetallic alloys, Ti-46.5Al-3Nb-2Cr-0.2W and Ti-25Al-10Nb-3V-1Mo, was examined as a function of strain rate and temperature. The compression strength of the Ti-25Al-10Nb-3V-1Mo intermetallic alloy was higher than Ti-46.5Al-3Nb-2Cr-0.2W alloy for most conditions. The mechanical behavior of the Ti-46.5Al-3Nb-2Cr-0.2W alloy exhibited three temperature-strain rate regimes. In contrast, the mechanical behavior of the Ti-25Al-10Nb-3V-1Mo alloy exhibited only two temperature-strain rate regimes. Anomalous temperature dependence of the yield stress was observed for both alloys. However, this effect increased for the Ti-46.5Al-3Nb-2Cr-0.2W alloy and decreased with increasing strain rate for the Ti-25Al-10Nb-3V-1Mo alloy, with increasing strain rate.
