| 摘 要： | 测量了具有双程记忆效应的Cu-298Zn-4Al(质量分数）合金的L－T曲线，用透射电镜观察了该合金在不同时效温度下的微观组织，计算并分析了该双程记忆合金弹簧的实用参数，以此为依据，设计研制了一种能够在油田使用的定温控制阀门，本阀门结构简单，动作可靠，适合控温精度要求不高且工作环境较恶劣的条件下使用，具有广泛的应用前景。

| Abstract: | Heating and cooling curves for the double-memory-type shape memory a lloy (SMA) Cu-29 8 Zn-4Al have been measured. The microstructure of the allo y aged at various temperatures have been investigated using TEM. After analyzing properties of the alloy, the application parameters of a double-memory-type s pring formed from it were calculated. Based on the experimental data a themo-co ntrol valve for oil-field use was designed. The valve can switch on or off aut omatically. of simple construction, it functions reliably and is suitable for us e in critical situations . |
