Study on Microstructures, Mechanical and Shape-memory Properties of Ni3Ta High-temperature Shape-memory Alloy [PDF]
, 2011 Ni3Ta合金广泛地用作高温结构材料中的强化相，如高温合金、复合材料等。但是最近的研究发现，该种合金具有高的马氏体转变温度和优异的形状记忆效应，显示出作为新型高温形状记忆合金的良好潜力。目前的研究表明，Ni3Ta合金具有三种结构，即四方结构、单斜结构和正交结构，但是到目前为止，关于这三种结构之间的转变行为仍没有详细的研究报道。此外，由于该种合金呈现较大的多晶脆性，这也制约了它的发展。因此本论文主要针对上述两个方面的问题进行了详细的研究，其具体的研究结果如下： Ni3Ta合金在经1200℃保温4小时后 ...
