Abstract

Textures in molybdenum-rhenium (Mo-Re) alloys are inevitable during thermal fabrication. [110] and [100] are common orientations in Mo-Re alloys and effect mechanical responses. However, orientation dependence of mechanical responses in Mo-Re alloys is not quite clear yet. To clarity this problem, micro-pillar compression tests are conducted in grains with orientation [100] and [110] separately. Orientation-dependent compressive properties are found in Mo-14Re and Mo-42Re (wt.%), but are not found in Mo and Mo-5Re, which may be attributed to activated multi-slip planes as increased Re. Solid solution effect of Re not only relies on orientations, but also on Re contents. Softening effect occurs in both [100] and [110] Mo-5Re. while, strong strengthening effect happens in [110] Mo-14Re and Mo-42Re. Our research clarifies that Mo-Re alloys with [110] orientation/texture could be preferred to obtain good strengthening effect.
