采用多层喷射沉积技术制备了6066Al/SiC_p板材和锭材,研究了轧制、挤压工艺和热处理制度对该材料组织和力学性能的影响。研究结果表明,SiC颗粒在基体中分布均匀,结合良好,界面无明显反应区;轧制和挤压是对喷射沉积材料有效的致密化工艺并能改善SiC颗粒在基体中的存在状态;材料在T6态获得拉伸强度为640MPa,屈服强度为580MPa,弹性模量为133GPs,延伸率为9.4％的优良力学性能。 The 6066Al / SiC_p plate and ingot were prepared by multi-layer spray deposition technology. The effects of rolling, extrusion and heat treatment on the microstructure and mechanical properties were investigated. The results show that the SiC particles are uniformly distributed and well bonded in the matrix, and there is no obvious reaction zone in the matrix. Rolling and extrusion are effective densification techniques for the spray deposited materials and can improve the existence of SiC particles in the matrix. T6 state tensile strength of 640MPa, yield strength of 580MPa, elastic modulus of 133GPs, elongation of 9.4% of the excellent mechanical properties.
