变形高温合金成分调控与冶金制备技术研究
Research on the Regulation of the Composition and Metallurgical Preparation Technology of Deformed Superalloys
摘要
Abstract
As key materials in the aerospace,energy,and national defense industries,the high-temperature strength,oxidation resistance,and creep resistance of deformed superalloys directly determine high-end equipment's service limits and reliability.In recent years,significant improvements in the properties of deformed superalloys have been driven by research at home and abroad focusing on alloy composition design,metallurgical process optimization,and advanced preparation techniques.In terms of alloy design,through high-entropy alloying,synergistic regulation of trace elements,and the aid of computational materials science,new Ni-Co-Cr-based high-entropy alloys and low-density alloys(density reduced by 10％)have been developed,significantly expanding high-temperature adaptability.In metallurgical preparation technology,a relatively mature three-stage smelting process has been established in China,and corresponding optimizations have been carried out for the one-stage and two-stage processes.High-performance,high-quality superalloys are produced through the combination of subsequent electro-slag remelting and directional solidification technology,rapid solidification technology,and the development of recycling technology for returned materials.In the future,intelligent design,developing ultra-high temperature(＞1 200 ℃)alloys,and green manufacturing throughout the entire life cycle will become key focus areas.This paper reviews the progress of research on deformed superalloys in recent years from material composition and metallurgical preparation technology,providing theoretical support for the development and engineering application of high-performance materials.关键词
