| 摘 要： | 文章研究了Cu-12Al-5Ni-1.6Mn-1Ti形状记忆合金马氏体逆相变时弛豫时间与升温速率的关系.实验结果表明,马氏体逆转变时,弛豫时间随升温速率的增大开始迅速衰减,当升温速率较大时,逐渐趋于一个稳定值.马氏体逆转变量越少,弛豫时间越短,分布参数越大,并逐渐趋近于Debye滞弹性弛豫.

| Abstract: | The relationship between the relaxation time of inverse martensitic transformation and the heating rate was studied for Cu-12Al-5Ni-1.6Mn-1Ti(wt.%) shape memory alloy.The experimental results show that the relaxation time of the inverse phase transformation decays quickly to an equilibrium value as the heating rate increases.The relaxation time becomes shorter,and the relaxation distributed parameter gradually increases and finally approaches to Debye anelastic relaxation with the decrease of the volume fra... |
