| Abstract: | With a split Hopkinson torsion tension combination bar apparatus, the constitutive relation of Fe base shape memory alloy was experimentally studied at different temperatures. The results indicate that (1) its strength and ductility decrease with rising temperature under torsion\|tension at a high strain rate; and (2) there is a interaction between torsion and tension, which descends as temperature rises. |
