超高温高强度MGH754合金板材研究现状及应用

摘要

Up to now, alloy MGH754 plate has been the structural material with the highest strength above 1 100℃which is used for combustion chamber. The said material has promising development potential for application in combustion chamber and is of great importance for increasing operation temperature of engines used for aerospace engineering. In this paper, the production process, evolution of the microstructure, high temperature properties and its development prospect were described.%　　MGH754合金板材是迄今为止1100℃以上最高强度的燃烧室构成材料，是一种具有很高发展潜力的燃烧室板材，对于未来提高航空航天发动机工作温度具有十分重要的意义。本文即对MGH754合金板材的制备工艺、微观组织衍化、高温性能及发展应用进行了综述。
