Abstract
Description
1.モリブデン0.05質量%でドープされたイリジウムは、ハフニウム0.001質量%でのドーピングにより、1800℃でのクリープ強さに関して改善される。この改善は、Hf 0.01〜0.1質量%でのドーピングの際に最も明らかに現れる。Hf 0.5質量%を上回るドーピングの場合に、合金の加工はより困難になる。
・Ir 99g及びHf 1gをはかり入れる
・水冷されたCuチル鋳型中へ装入する
・真空排気する
・アルゴン300mbarでフラッディングする
・アークを点火し、合金を溶融させる
・均質な合金を得るために、何度も再溶融させる
ことによって行われる。
純イリジウムからなる1mmの厚さの板からなる試料を、圧延及び20分/1400℃の仕上げ焼きなまし後に、金属組織学的に断面を調べた。試料は、0.7mmの平均粒度を有する均一に再結晶された構造を示した。
