| 摘要 | The effect of constraint transformation heating temperature T-h on the free reverse transformation behaviour of 10% trained Ti44Ni47Nb9 alloy was investigated, and the experimental results showed that after the first constraint transformation the strained Ti44Ni47Nb9 alloy exhibits two separate recovery strains epsilon(r1) and epsilon(r2) on subsequent free reverse transformation, which increases and decreases with increasing T-h, respectively. However, the total recovery strain epsilon(r) (epsilon(r) =epsilon(r1)+epsilon(r2)) of Ti44Ni47Nb9 alloy decreases with increasing T-h. The plastic strain of Ti44Ni47Nb9 alloy is increased by the deformation of martensite under the recovery stress during the constraint transformation, which decreases epsilon(r) strain of Ti44Ni47Nb9 alloy. Since the martensite of strained Ti44Ni47Nb9 alloy is consisted of M1 and M2 oriented martensites with different strain levels after the first constraint transformation, strains epsilon(r1) and epsilon(r2) are related to M1 and M2 oriented martensite reverse transformations respectively. |
