以80vol%碳化硅和20vol%氮化硅的混合物作为增强体,在建筑用6005铝合金基体中添加了5vol%增强体,采用搅拌摩擦加工方法,制备了建筑用新型铝基复合材料,并进行了显微组织、物相组成和力学性能的研究。结果表明,搅拌摩擦加工方法可制备出具有较高力学性能的建筑用新型铝基复合材料,该复合材料由α-Al、碳化硅(SiC)和氮化硅(α-Si_3N_4)组成,其室温抗拉强度、屈服强度和伸长率分别为527 MPa、503 MPa、7.2%。
With a mixture of 80vol% silicon carbide and 20vol% silicon nitride as a reinforcement, a 5vol% reinforcing body was added to 6005 aluminum alloy substrate for construction and a novel aluminum-based composite material for construction was prepared by a friction stir processing method The microstructure, phase composition and mechanical properties of the study. The results show that the friction stir processing method can be used to prepare a new type of aluminum matrix composite material with high mechanical properties. The composite material consists of α-Al, silicon carbide (SiC) and silicon nitride (α-Si_3N_4) Tensile strength, yield strength and elongation were 527 MPa, 503 MPa, 7.2%, respectively.
