| 摘 要： | 研究了Ｆｅ－Ｍｎ－Ｓｉ形状记忆合金热塑性。结果表明：合金中硅含量的增加可提高合金的记忆效应，却严重损害合金热塑性；微量元素Ｍｇ的加入可大大改善合金的热塑性，而不降低记忆效应。由于Ｍｇ元素的加入，含Ｓｉ量达４％的Ｆｅ－Ｍｎ－Ｓｉ形状记忆合金也能顺利地热轧成无缝管，提高了Ｆｅ－Ｍｎ－Ｓｉ形状记忆合金实用性。

| Abstract: | Thermoplasticity of Fe-Mn-Si shape memory alloys has been investigated. The experimental results show that the shape memory effect (SME)increases but thermoplasticity decreases with the increasing of Silicon content in Fe-Mn-Si shape memory alloys. Thermoplasticity of these alloys can be improved apparently but SEM not be devastated by adding of microelement Magnesium, because of thermoplasticity being improved by adding of microelement Magnesium.Fe-Mn-Si alloys with 4% Silicon content can be rolled successfully to be seamless steel pipes. So Fe-Mn-Si shape memory alloys show a good applied prospect. |
