When specimens were deformed above Af, complete pseudoelasticity might be obtained theoretically, which might be damaged, h...

在拉力试验机上用电测法测绘了Cu-Zn-Al合金在马氏体相变点上下各温度的σ-ε曲线，所得主要结果如下：(1)试样在M_s与M_d之间加载，随着温度升高，诱发马氏体相变所需临界应力增大，且加载温度与临界应力之间存在着线性关系；(2)在A_f点以上加载，理论上可获得完全的伪弹性，但加载温度过高或应变量过大，均会损害伪弹性；(3)试样在M_s点上下温度区域变形，得到的伪弹性回复和形状记忆回复之和在80%以上，但在M_s点附近总回复量出现一极小值，且伪弹性回复在M_f点以下又有所回升。

经比较可以发现当浓度降低其节能效率下降、临界溶解温度范围提高、反应速度加快，虽然浓度降低仍可以达到节能的目的且反应速度加快，但临界溶解温度范围提高可能使实际运用上会有所困难，有机会产生节能窗材无法相分离的情形，加上在低体积莫耳浓度时相分离后水胶粒子会沉淀的现象，使节能窗材无法顺利运作，故实际运用上不适合降低节能窗材的浓度。

After hot carrier stress, devices were evaluated by using positive bias temperature instability test. With different trends in the time evolution of threshold voltage shift and sub-threshold swing degradation, it is found that electron trapping in the HfO2 is the major reason for the threshold voltage variation. Compared to control devices, devices with fluorine and nitrogen exhibit good passivation at the interface. Devices were measured at an elevated temperature.
