日本 Toyohashi 技术大学和神户钢有限公司联合研制了一种新型耐热钛合金(用钽替代1%Nb),它比普通钛合金的使用寿命提高了3～5倍。该种新合金的最高使用温度已超过600℃。钛合金重量轻,比强高,适用于重要飞机件材料,尤其这种高温合金特别适用于火箭发努机构件,例如,叶盘和叶片。IMI-829、IMI-834钛合金是 IMI 钛有限公司率先研制的。新合金具有极好的高温强度和蠕变性能,据说它的性能还不止如此。
Japan Toyohashi University of Technology and Kobe Steel Co., Ltd. jointly developed a new type of heat-resistant titanium alloy (with 1% Nb replaced by tantalum), which is 3 to 5 times longer than ordinary titanium alloys. The maximum temperature of the new alloy has exceeded 600 ℃. Titanium light weight, high strength, suitable for important aircraft parts materials, especially the superalloy especially suitable for rocket engine parts, such as leaves and leaves. IMI-829, IMI-834 titanium alloy is the first developed by IMI Titanium Co., Ltd. The new alloy has excellent high temperature strength and creep performance, it is said that its performance is more than that.
