Interfacial reactions of the Ni/AuSn/Ni and Cu/AuSn/Ni joints are experimentally studied at 330℃for various reflow *** microstructures and mechanical properties of the as-solidified solder joints are *** as-solidified solder matrix of Ni/AuSn/Ni presents a typical eutecticξ-(Au,Ni)5Sn+δ-(Au,Ni)Sn lamellar microstructure after reflow at 330℃for 30 *** reflow for 60 s,a thin and flat(Ni,Au)3Sn2intermetallic compound(IMC) layer is formed,and some needle-like(Ni,Au)3Sn2phases grow from the IMC layer into the solder *** the other hand,a cellular-typeξ(Cu) layer is found at the upper AuSn/Cu interface in the Cu/AuSn/Ni joint after reflow for 30 s,and a(Ni,Au,Cu)3Sn2IMC layer is also formed at the lower AuSn/Ni interface. For both joints the IMC layer grows significantly with the increase of reflow time,but the growth rate of(Ni,Au,Cu)3Sn2IMC in the Cu/AuSn/Ni joint is smaller than that of the(Ni,Au)3Sn2layer in the Ni/AuSn/Ni *** comparisons of the shear strength and fracture surface between the Ni/AuSn/Ni and Cu/AuSn/Ni joints suggest that the coupling effect of the Cu/AuSn/Ni sandwich joint is helpful to prevent the excessive growth of(Ni,Au)3Sn2,which in turn enhances the mechanical reliability of the solder joint.

PBL连接件作为主要的传力构件被广泛应用于钢-混组合桥梁结构中,为研究基于大直径混凝土榫的PBL连接件力学性能,设计了8组共24个试件,对其进行推出试验研究。根据推出试件的内部破坏状态分析了大直径混凝土榫PBL连接件的破坏形态及破坏机理;探讨了大直径混凝土榫PBL连接件抗滑移性能及承载能力的影响因素;从荷载-滑移曲线特征、抗剪刚度及延性性能三方面对比分析了不同直径混凝土榫PBL连接件的力学性能。研究结果表明:大直径混凝土榫PBL连接件的主要破坏形式有横向贯穿钢筋的剪断破坏、孔内混凝土的压碎破坏及开孔剪切钢板的受剪破坏3种;横向贯穿钢筋直径、开孔剪切钢板厚度及其破坏形态均为影响PBL连接件抗滑移性能的重要因素,剪切钢板的开孔直径对PBL连接件抗滑移性能的影响较小;横向贯穿钢筋直径、开孔剪切钢板厚度及其开孔直径是影响PBL连接件承载能力的重要因素;在大直径混凝土榫PBL连接件中,钢板开孔直径为75mm的PBL连接件的力学性能优于钢板开孔直径为60mm的,而钢板开孔直径为90mm的PBL连接件的力学性能优于钢板开孔直径为75mm的。研究结果为大直径混凝土榫PBL连接件的工程应用奠定了理论依据。
