镥对铂性能的强化作用

Strengthened Pt by adding Lu

研究了含０．０３～１ｗｔ％Ｌｕ对Ｐｔ的力学和电学性能的影响。含Ｌｕ量较低时，晶界偏析严重，各项性能降低。含Ｌｕ量高的合金，Ｌｕ对Ｐｔ有很大的强化作用，室温强度和电阻率显著增加，高温下有很高的抗蠕变能力。

Effect of Lu on the mechanical and electric properties of Pt was studied.The range of concentration of Lu was 0.03～1wt%.In the case of low Lu concentration,the strength and resistivity of platinum are decrease because of the intergranular segregation.But in case of high concentration,the strength and resistivity of platinum increase,as well as high temperature creep resistance.
