Research Progress of Mo-Re Alloys

摘要:

“Re效应”使得Mo的理化、热电、力学、加工焊接性能得到全面改善。Mo-Re合金由于具有良好的综合性能，被广泛应用于先进核能、航天航空、电子工业、生物医用等领域。尤其是优异的抗辐照性能、与核燃料及碱金属冷却剂的相容性、中子特性等核物理性能，使其成为空间核反应堆堆芯结构材料的首选。本文从晶体结构、组织性能、制备加工及应用四个方面系统综述了Mo-Re合金的研究现状，并对其发展前景进行了展望。

Abstract:

The "Re effect" makes the physical and chemical, thermoelectric, mechanical, and processing and welding properties of Mo have been comprehensively improved. Mo-Re alloys are widely used in advanced nuclear energy, aerospace, electronics, biomedical and other fields due to their good comprehensive properties. In particular, its excellent radiation resistance, compatibility with nuclear fuels and alkali metal coolants, neutron characteristics and other nuclear physical properties make it the first choice for core structural materials in space nuclear reactors. In this paper, the research status of Mo-Re alloys is systematically reviewed from four aspects: crystal structure, microstructure, properties, preparation, processing and application, and its development prospect is prospected.
