形状记忆合金的研究正方兴未艾,研究领域包括冶炼、加工、热处理等许多方面。对形状记忆合金的转变机制、热处理工艺、力学性能已进行了许多研究,有大量的文献报道,但对其耐蚀性的研究,至今未见报道。本工作设计了一种新型的CuZnAlNi形状记忆合金,对其在常见介质巾的耐蚀性进行研究。一、实验材料合金在中频电磁感应炉中熔炼。原料为:99.9%电解铜,99.9%纯锌,1号工业纯铝99.7%,99.9纯Ni。按设计好的成份依次加入Cu、Al、Ni、Zn,最后浇铸成50×70×220mm的长方锭,铸锭脱模后,在箱
Research on shape memory alloys is in the ascendant. His research interests include many aspects such as smelting, processing and heat treatment. Many studies have been carried out on the transformation mechanism, heat treatment process and mechanical properties of shape memory alloys. There is a large amount of literature reported, but the research on its corrosion resistance has not been reported yet. In this work, a new type of CuZnAlNi shape memory alloy was designed and its corrosion resistance in common media was studied. First, the experimental material alloy smelting in the intermediate frequency electromagnetic induction furnace. Raw materials: 99.9% electrolytic copper, 99.9% pure zinc, industrial grade 1 99.7%, 99.9 pure Ni. According to the design of the ingredients followed by the addition of Cu, Al, Ni, Zn, and finally cast into a 50 × 70 × 220mm ingot, ingot demoulding, in the box
