摘要
标题合金加入Ｚｒ、Ｂ后，在１１００～１２００℃，高温性能优于Ｐｔ－７Ｒｈ合金。Ｚｒ、Ｂ元素在合金中主要起固溶强化作用。就高温强度性质而言，该合金可替代Ｐｔ－７Ｒｈ合金，从而节约２～３ｗｔ％的Ｒｈ。
It has been found that the high temperatare properties were better than the Pt 7Rh alloy in 1100～1200℃ when the Zr、B elements had been added into Pt (3～5)Rh alloys. The Zr、B elements will be solved in the solid solution of the Pt (3～5)Rh alloys. The Pt 7Rh alloy can be insteaded by the Pt (3～5)Rh Zr B alloys, so that 2～3wt% Pt can be saved.
