Title: Chromium-iron single crystal alloy and gas turbine member using the same
Inventor: SUZUKI KUNITERU
IPC: F02C7/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To obtain a chromium-iron alloy excellent in mechanical properties at high temp., particularly creep rupture characteristic, high temp. oxidation resistance, etc., and suitable for gas turbine member, etc., by regulating chromium content to a high value in a specific range in a chromium-iron binary alloy and forming a single crystal free from grain boundaries. SOLUTION: This alloy is a chromium-iron single crystal alloy having a composition consisting of, by weight, 60-95% chromium and the balance essentially iron. As to chromium content, creep rupture characteristic at high temp. becomes insufficient and a region embrittled by the presence of Σ-phase is brought about when it is below 60%, and on the other hand, hardness is deteriorated when it exceeds 95%. Because of the absence of grain boundaries in this chromium-iron single crystal alloy, intergranular fracture does not occur and this alloy becomes excellent in high temp. oxidation resistance as well as in mechanical properties at high temp. in particular. By using a gas turbine member composed of this alloy, a high-powered and high-efficiency gas turbine can be obtained. Further, it is preferable to regulate the contents of the elements other than chromium and iron to <=0.1wt.%.
