In the present work, the processing of microwave castings of Cu–Mo-based materials was carried out using microwave heating at 2.45 GHz and 900 W. Three sets of castings were developed inside microwave applicator cavity with three different compositions such as Cu + 10% Mo, Cu + 30% Mo and Cu + 50% Mo by volume percentage. A mechanism describing microwave metal interaction has been established. Microstructure analysis study of developed castings revealed the formation of small equiaxed grains with uniform dispersion of Mo particles in Cu-based metal matrix. The presence of Cu₆₄O, Cu₆Mo₅O₁₈ and MoO₂ elements phases was observed during phase analysis of microwave processed composite castings. Vicker’s microhardness study analysis revealed that the Cu + 50% Mo-based casting exhibited maximum Vicker’s microhardness of order 120.8 ± 9 HV, which was approximately 2.7 times that of microwave processed Cu-based castings. The higher percentage of Mo particles inside Cu-based matrix resulted in an increase in electrical resistivity of the casting.

在当前工作中，使用2.45 GHz和900 W的微波加热对Cu-Mo基材料的微波铸件进行了处理。在微波辐射器腔体内开发了三组铸件，其中三种组分分别为Cu + 10％ Mo，Cu + 30％Mo和Cu + 50％Mo（按体积百分比计）。建立了描述微波金属相互作用的机制。对已开发铸件的显微组织分析研究表明，在铜基金属基体中形成了均匀分布的Mo颗粒小的等轴晶粒。Cu ₆₄ O，Cu ₆ Mo ₅ O ₁₈和MoO _2的存在在微波处理的复合铸件的相分析过程中观察到元素相。维氏的显微硬度研究分析表明，Cu + 50％Mo基铸件的最大维氏显微硬度为120.8±9 HV，约为微波处理的铜基铸件的2.7倍。在基于铜的基体中较高百分比的钼颗粒导致铸件的电阻率增加。
