日本东北大学金属材料研究所开发成功轻质耐热新合金 ,适于制航空发动机涡轮机叶片之用 ,是由高纯铁和高纯铬熔化后合成的 ,在 1 2 0 0℃高温下还具有较好的强度和耐热性。现正由三菱重工业公司试用 ,可用普通车床加工 ,有望成为超耐热合金。此种叶片属耐热合金系 ,由 99.995% Institute of Metal Materials, Northeastern University, Japan, the successful development of lightweight heat-resistant alloys suitable for the manufacture of aero-engine turbine blades, is synthesized by melting high-purity iron and high-purity chromium, also has good at 1200 ℃ high temperature The strength and heat resistance. Now trial by the Mitsubishi Heavy Industries, can be used ordinary lathe processing, is expected to become superalloy. Such leaves are heat-resistant alloy, from 99.995%
