摘要
在室温下通过实验研究了63Sn-37Pb钎料合金在具有不同保持时间、应变率、应变幅值、应变-时间、加载波形及加载历史下的循环变形行为.研究表明:该钎料具有明显的应变率敏感性;其单轴循环变形的瞬态行为受到保持时间、加载波形以及应变幅值的影响;该钎料合金循环变形行为的加载历史依赖性不明显.
The uniaxial cyclic deformation behaviors of 63Sn-37Pb solder alloy were experimentally investigated under different dwell times, strain rates, strain amplitudes, strain-time loading waveforms and loading histories. The study shows that the solder alloy has a significant strain-rate sensitivity, its instant deformation behavior under uniaxial cyclic loading is dependent on dwell time, loading waveform and strain amplitude, but the dependence of the cyclic deformation behavior on loading history is not significant.
