摘 要: 在不同溫度進(jìn)行軋制復(fù)合及擴(kuò)散處理制備了Ag/Cu層狀復(fù)合材料，研究了反復(fù)彎曲載荷條件下材料結(jié)合性能與復(fù)層基體硬度及界面區(qū)域微觀組織的關(guān)系。溫度合適的復(fù)合及擴(kuò)散可使材料基體具有充分的再結(jié)晶組織、較低的硬度、致密的界面結(jié)合形態(tài)，因而能使材料具有較優(yōu)良的結(jié)合性能。溫度過(guò)高的復(fù)合及擴(kuò)散處理可導(dǎo)致界面上存在較厚的氧化層及較多的空洞，基體內(nèi)也會(huì)形成粗大晶粒，這些均會(huì)明顯損害結(jié)合性能。

Abstract:The Ag/Cu bimetallic laminates were prepared by roll bonding and diffusion treatment at different temperatures. The dependence of the bond properties under the repeatedly bonding condition on the matrix hardness of strip components and the microstructure in interface region was investigated. The bonding and diffusing at optimum temperatures produce the high bond properties because the laminates show full recrystallization，low hardness and tightly bonding interface. Bonding and diffusing to excessively high temperature result in the thick oxide layer on the interface， more pores along the interface and coarse grains in the matrixes Ag and Cu. Consequently，the bond properties may be reduced significantly.
