Abstract

SiC particles-reinforced Al matrix composites (SiC/AMCs) have been widely used in the aerospace structural components. In this work, 20 vol% SiC/2A14 joint was fabricated by laser welding technology. The effects of different laser power/welding velocity on the 20 vol% SiC/2A14 joint forming, microstructure evolution and mechanical properties were studied in detail. The results showed that, under the same heat input, the high power/high welding velocity was beneficial to reduce the porosity of SiC/2A14 joint and inhibited the formation of brittle phase of AlC. At 8 kW-133 mm/s welding parameters, the maximum tensile strength of the SiC/2A14 joint reached 199 MPa, which is ~64% higher than that of the SiC/2A14 joint prepared at 4 kW-66 mm/s welding parameters. By analyzing the fracture morphology and SEM image of SiCp/2A14 joint section, it is was found that the porosity of weld and AlC brittle phase were the important factors limiting the strength of SiCp/2A14 joint. This work provides a reference for the process window design of laser welding SiC/2A14 composites.

摘要

碳化硅颗粒增强铝基复合材料（SiC/AMCs）已广泛应用于航空航天结构部件。在本研究中，采用激光焊接技术制备了20体积分数的SiC/2A14接头。详细研究了不同激光功率/焊接速度对20体积分数SiC/2A14接头成型、微观结构演变及力学性能的影响。结果表明，在相同热输入条件下，高功率/高焊接速度有利于降低SiC/2A14接头的气孔率，并抑制AlC脆性相的形成。在8kW-133mm/s焊接参数下，SiC/2A14接头的最大抗拉强度达到199MPa，比在4kW-66mm/s焊接参数下制备的SiC/2A14接头高出约64%。通过分析SiCp/2A14接头截面的断口形貌和扫描电镜图像，发现焊缝气孔率和AlC脆性相是限制SiCp/2A14接头强度的重要因素。本研究为激光焊接SiC/2A14复合材料的工艺窗口设计提供了参考。
