Description
まず、各原料粉末(Ir粉末、Rh粉末、Ru粉末、Nb粉末、Ni粉末)を所定の割合で混合し、混合粉末を作製した。次いで、得られた混合粉末を、一軸加圧成形機を用いて成形し圧粉体を得た。得られた圧粉体をアーク溶解法により溶解し、インゴットを作製した。
とし、高温強度比T(%)を、T=Tx/T0×100の式から求め、表2に示した。ここで、高温強度に優れるとは、具体的には、上述する式に従って算出される高温強度比T(%)が、130以上、好ましくは140以上であることを意味する。
Claims (1)
- Rhを5~35mass%、
Ruを0.1~25mass%、
Nbを0.1~3mass%、
Niを0~4mass%含有し、
残部がIrである、
ことを特徴とするIr合金。
