摘 要: 鉬材料具有導(dǎo)熱導(dǎo)電性能好、高強(qiáng)度、高熔點(diǎn)等優(yōu)點(diǎn)，廣泛應(yīng)用于諸多領(lǐng)域，例如，在核能和航空航天工業(yè)中用于制造聚變反應(yīng)器轉(zhuǎn)向器部件和導(dǎo)彈燃燒室等，在機(jī)械工業(yè)中用做刀具等零件。但是，當(dāng)鉬材料在高溫條件下時(shí)，其抗蠕變性能、高溫強(qiáng)度以及抗氧化性能都會(huì)顯著下降，很大程度上影響了材料在諸多領(lǐng)域中的應(yīng)用。本文主要綜述了用不同的方法來(lái)提高鉬基材料的強(qiáng)韌性，包括合金化、第二相彌散和大塑性變形，介紹了這些方法的機(jī)理和對(duì)鉬材料的改善效果，并對(duì)未來(lái)鉬基材料強(qiáng)韌化研究方向做出了展望。

Abstract:Molybdenum material has the advantages of good thermal conductivity, high strength, high melting point and so on, which is widely used in many fields, for example, in the nuclear and aerospace industries for the manufacture of convergent reactor diverter components and missile combustion chamber; in the machinery industry for cutting tools and other parts. However, when the molybdenum material under high temperature conditions, its creep resistance, high temperature strength and antioxidant properties will be significantly reduced, affecting the application of the material in many fields to a great extent. This article mainly reviewed the use of different methods to improve the toughness of molybdenum-based materials, including alloying, second-phase dispersion and severe plastic deformation, the mechanism of these methods and the improvement effect of molybdenum materials were introduced, and the future research direction of molybdenum-based materials was forecasted.
Key words: molybdenum-based materials; toughening; alloying; second-phase dispersion; severe plastic deformation
