Adelaide Nespoli等人首先对Ni_(56)Mn_((25-x))Ga_(19)Co_x(x=0%,2%,4%(原子分数))进行完全退火,然而通过不同加热工艺制造各种样品。研究结果表明,经淬火和随后高加热速度可以提高所研究高温磁控形状记忆合金的热响应特性,提高它的热弹性转变的稳定性。本研究还发现,慢速热循环对于钴掺杂高温磁控形状记忆的奥氏体时效是有利的。
Adelaide Nespoli et al. First completely annealed Ni_ (56) Mn_ ((25-x)) Ga_ (19) Co_x with x = 0%, 2% and 4% (atomic fraction) Kind of sample The results show that the quenching and subsequent high heating rate can improve the thermal response characteristics of the high-temperature magnetron shape memory alloy and increase the stability of its thermoelastic transformation. This study also found that slow thermal cycling is beneficial for the austenitic aging of cobalt doped high temperature magnetron shape memory.
