含少量氮的Ti-10 V-2Fe-3Al合金表现出超弹性。从固溶处理温度开始控制冷却速度，可提高Ti-10 V-2Fe-3Al和Ti-10 V-2Fe-3-Al-0.2N合金的超弹性。在这项研究中，一个更广泛的冷却速度范围内进行了检查，并在缓慢冷却过程中的显微组织变化进行了研究，通过检查淬火和时效试样的硬度和电阻率测量和透射电子显微镜。尽管无N合金的超弹性随着冷却速率的降低而提高，冷却速率高达22 K/s，0.2N合金的冷却速率高达50 K/s，但显微组织没有明显变化。在超弹性得到改善的温度范围内淬火和时效试样的观察表明，相分解是通过等温！相沉淀因此，认为缓冷过程中的组织演变是等温析出过程。或其前体现象。(doi：10.2320/matertrans.MA200909）
A Ti-10V-2Fe-3Al alloy with a small amount of nitrogen shows superelasticity. Controlling of the cooling rate fromsolution treatment temperature improves superelasticity in both Ti-10V-2Fe-3Al and Ti-10V-2Fe3-Al-0.2N alloys. In this study, a wider range of the cooling rate was examined and microstructure change during slow cooling was investigated through examining quenched and aged specimens by means of hardness and resistivity measurement and transmission electron microscopy. Although superelasticity is improved with a decrease in the cooling rate up to 22 K/s for the N-free alloy and up to 50 K/s for the 0.2N alloy, there is no obvious change in microstructure. It is clarified from the observation of specimens quenched and aged at the temperature range where superelasticity is improved that thephase decomposition occurs through isothermal ! phase precipitation. Therefore, microstructure evolution during slow cooling is considered to be precipitation of isothermal ! phase or its precursor phenomena. (doi:10.2320/matertrans.MA200909)
