Abstract

The copper-beryllium alloys were usually processed by thermal treatments. Herein, inspired by promising ultrasonic effects, we investigate the microstructures and properties of the cast Cu-0.2Be-1.0Co alloy under different ultrasonic solidification conditions. It is found that, with intense ultrasonic treatments, the microhardness, micro-compressive performance and wear resistance exhibit significant improvements. The coarse α(Cu) dendrites in the cast alloy are greatly refined, fragmented and even converted into equiaxed grain structures without preferred crystal orientations. Moreover, the grain size greatly decreases from 1673.6 μm to 103.8 μm and dense dislocations occur. These microstructural transitions and resultant property enhancements can be attributed to acoustic cavitation, acoustic streaming and high-frequency vibration induced by ultrasonic field. The results in this work indicate that the ultrasonic effects can modulate the microstructures and improve the properties of the cast low-beryllium copper alloys effectively.

超声对Cu-0.2Be-1.0Co铸造合金组织与性能的影响

铜铍合金通常采用热处理工艺。受超声效果的启发，研究了不同超声凝固条件下铸态Cu-0.2Be-1.0Co合金的组织和性能。结果表明，经强超声处理后，合金的显微硬度、微压缩性能和耐磨性均有显著提高。铸态合金中粗大的α(Cu)枝晶被大大细化、破碎，甚至转变为等轴晶组织，无择优取向。晶粒尺寸从1673.6 μm大幅减小至103.8 μm，出现密集位错。这些微观结构转变和由此产生的性能增强可归因于声空化、声流和超声场引起的高频振动。结果表明，超声作用能有效地调节铸态低铍铜合金的显微组织，提高铸态低铍铜合金的性能。图形抽象

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
