摘要
Abstract
Single crystal superalloys exhibit excellent comprehensive properties and have been widely applied in advanced aero-engines.This paper reviews the development of single crystal superalloys from the aspects of strengthening mechanism and composition design,directional solidification and crystal growth,solid-state phase transformation and heat treatment and mechanical behaviour.Special emphasis is placed on the research progress of the high-performance,low-cost single crystal superalloys with independent intellectual property rights of China developed by Beijing Institute of Aeronautical Materials,and future development direction of single crystal superalloys are discussed.关键词
