高温高熵合金研究进展
Research progress in high-temperature high-entropy alloys
摘要
Abstract
High-temperature high-entropy alloys(HEAs)show potential to surpass traditional Ni-based alloys through multi-principal element synergy and microstructural regulation.This review systematically examines three systems:high-entropy superalloys(HESAs),refractory HEAs(RHEAs)and refractory high-entropy superalloys(RSAs).HESAs emulate the γ/γ′ dual-phase structure of Ni-based alloys,achieving comparable strength at 800-1000℃.RHEAs utilize refractory elements to form high-melting-point solid solutions with superior performance above 1200℃.RSAs innovate with BCC/B2 nanobasket structures,outperforming Ni-based alloys across 25-1200℃.Current challenges include poor room-temperature ductility,oxidation resistance and phase stability,demanding breakthroughs in multi-scale microstructure control,dynamic phase transformation mechanisms and high-throughput design.Future directions prioritize multi-objective composition optimization,advanced processing,cross-scale characterization,and service-condition evaluation systems to guide extreme-environment applications like aeroengine components and nuclear reactors,etc.关键词
