Abstract

Molybdenum–copper (MoCu) composites have a low coefficient of thermal expansion, good electrical and thermal conductivity and mechanical properties, and are widely used in microelectronic packaging heat dissipation materials, aerospace and other fields. Due to the large difference in the properties of Mo and Cu, the deformation of MoCu composites is difficult. At present, there is a lack of research on the deformation process and property changes of MoCu composites with large deformation. In this study, 74 % MoCu30 composites with large deformation are prepared by cyclic warm rolling, and the deformed materials have excellent mechanical and physical properties, and the evolution of the microstructure of the composites during the deformation process is described.

循环热轧：获得 MoCu 复合材料优异性能的途径

钼铜（MoCu）复合材料具有较低的热膨胀系数、良好的导电导热性能和机械性能，被广泛应用于微电子封装散热材料、航空航天等领域。由于 Mo 和 Cu 的性能差异较大，MoCu 复合材料变形困难。目前，还缺乏对 MoCu 复合材料大变形过程和性能变化的研究。本研究采用循环热轧法制备了 74 % MoCu30 大变形复合材料，变形材料具有优异的力学和物理性能，并描述了复合材料在变形过程中微观结构的演变。

期刊介绍： The International Journal of Refractory Metals and Hard Materials (IJRMHM) publishes original research articles concerned with all aspects of refractory metals and hard materials. Refractory metals are defined as metals with melting points higher than 1800 °C. These are tungsten, molybdenum, chromium, tantalum, niobium, hafnium, and rhenium, as well as many compounds and alloys based thereupon. Hard materials that are included in the scope of this journal are defined as materials with hardness values higher than 1000 kg/mm2, primarily intended for applications as manufacturing tools or wear resistant components in mechanical systems. Thus they encompass carbides, nitrides and borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder. Ceramics and superhard materials including diamond and cubic boron nitride may also be accepted provided the subject material is presented as hard materials as defined above.
