探讨了0Cr12Ni6Mn16Si5形状记忆合金的工业化生产工艺,0Cr12Ni6Mn16Si5可以采用EF1+AOD+EF2进行冶炼.合金具有强的热敏感性和高温变形抗力,高温可加工热塑性温度区间比较窄,温度超过1*!100℃,塑性直线下降.铸锭的开锻温度为1*!080℃,终锻温度为900℃;锻造管坯只有采用挤压方法实施管材成型.挤压成型的毛管可以采用冷轧与冷拔相接合方法进一步加工成薄壁管. 相似文献

Effect of Cu addition on corrosion resistance and shape memory effect of Fe- 14Mn-5 Si-9Cr-5Ni alloy
The modification of Fe-14Mn-5Si-9Cr-5Ni shape memory alloys(SMAs) by copper addition was carried out, aiming at further enhancing its corrosion resistance. The results of electrochemical potentiodynamic measurement and immersion test show that copper can remarkably improve the corrosion resistance in Cl- solution. Otherwise, it is found that copper cannot markedly affect the mechanical properties nor the shape memory effect(SME). As for the effects of copper on Fe-Mn-Si based alloys, the austenite strengthening is one of the key factors to improve SME. 相似文献
