The superelastic properties of NiTi thin films prepared with sputtering were studied. To characterize their superelasticity, tensile and bulging and indentation tests were performed. The measured mechanisms using these three methods were compared, and the factors that influence superelasticity were described.

The erosion behaviour of TiNi alloy foils (Ni: 50.5 at pct, thickness: 70-90 mu m) under various heat treatments has been studied with two different tests: sand-blasting erosion (SBE) with impingement angle of 30 degrees and slurry erosion (SE). The erosion resistance of the foils aged at 400-450 degrees C/30 min is the best in all tests. The quenched foil is also good in the SBE test, but not so good in the SE test. The slurry-erosion resistance of the aged foils is better than that of L214 with high hardness. All the foils exhibit much better erosion resistance than 18Cr-8Ni stainless steel in the tests.

利用显微组织分析、示差扫描量热法(DSC)和振动样品磁力计(VSM)研究了Co28Ni34Al28-xSnx(x=1,2,3)合金在应力作用下的马氏体相变行为,分析了Sn元素的含量x对合金马氏体相变以及居里点的影响.Co38Ni34Al28合金的居里点随着Sn的含量增加而升高,合金在室温下处于亚稳状态的温度范围加宽,因此在室温下施加应力更容易触发合金马氏体相变.
