Effect of deformation strain on transformation hysteresis in Cu-base shape memory alloy

形变对铜基形状记忆合金相变滞后宽度的影响

During the training procedure the transformation temperatures and hysteresis are measured by differential scanning calorimetry ( DSC ) .

在训练过程中,作者用示差扫描量热法 ( DifferentialScanningCalorimetry,DSC ) 研究了不同热力学训练的试样.

The relationships of R, M transformation temperature, hysteresis, transformation heat and aging temperature, aging time were given out.

给出了R、M相变温度、热滞、相变热与时效温度、时效时间的关系。

The martensitic transformation temperatures could be considerably increased by increasing Mn and decreasing Ga with fixed Ni content, while the temperature hysteresis becomes narrow and Curie temperature keeps constant.

保持Ni含量不变，增加Mn，降低Ga含量会使马氏体相变温度明显提高，同时相变滞后温区减小，居里温度基本不变。

On the other hand, the Ti-Ni-Cu alloys show narrow transformation temperature hysteresis and relatively high martensitic transformation temperature.

另一方面，Ti-Ni-Cu三元形状记忆合金则拥有较高的相变温度和较窄的相变温度迟滞，可以作为很好的驱动材料。

In Ni-rich Ti_49. 4Ni_50. 6 film R phase transformation temperature and the thermal hysteresis of both R phase and martensitic transformation decrease with increasing the aging temperature, while the martensitic transformation temperature increases.

Ti（49.4）Ni（50.6）薄膜R相变温度降低，马氏体相变温度升高，R相变和马氏体相变热滞降低。
