选区激光熔化制备20％SiC颗粒增强铝基复合材料的工艺优化及性能研究
Study on the Process Optimization and Properties of 20 vol.％SiC Particle Reinforced Aluminium Matrix Composites Prepared by Selective Laser Melting
摘要
Abstract
Parts formed via selective laser melting(SLM)technology exhibit rapid solidification characteristics while enabling the fabrication of complex geometries,making it widely applicable in the aerospace,automotive,and medical fields.Thus,a 20 vol.％SiC particle-reinforced AlSi10Mg composite was developed via SLM to investigate how varying scanning speeds and laser powers affect microstructure and mechanical properties.The results indicate that the hardness fluctuates between 160～175 HV depending on the laser power.At the 1 000 mm/s scanning speed,the hardness of the material gradually increases,reaching a peak of 172.3 HV at 410 W.However,at the 1 200 mm/s scanning speed,the hardness significantly varies,reaching a maximum of 171.2 HV at 390 W.Notably,the samples processed at 390 W and 1 200 mm/s present fewer internal cracks and pores,with SiC particles uniformly distributed within the aluminium matrix and forming an ideal fusion interface.关键词
