Combined experimental and theoretical study on the effect of Nb content on martensitic transformation of NbRu shape memory alloys 下载免费PDF全文
The effect of Nb content on the martensitic transformation
of NbRu high-temperature shape memory alloys is investigated by
experiments and first-principles calculations. We calculate the
lattice parameters, density of states, charge density, and heats of
formation of Nb50+xRu50-x β phase. The
results show that an increase in Nb content increases the stability
of Nb50+xRu50-x β phase, leading to a
significant decrease of the β to β' martensitic
transformation temperature. In addition, the mechanism of the
effects of Nb content on phase stability and martensitic
transformation temperature is studied on the basis of
electronic structure. 相似文献
