The effect of orientation and that of tensile vs. compressive stress on the B2-B19' stress-induced martensitic transformation was investigated by using tensile test for solution-treated Ti-50.8at%Ni single crystals, and the result was analyzed by comparing Schmid factors for competing two shears, i.e. for the shape strain of martensitic transformation and for slip. As a result, complete superelasticity was found for compression even in a solution-treated single crystal, although complete superealsticity was not found for tension. |
