摘　　要：测定了铝合金的微型剪切试验和拉伸试验的性能参数,研究了这些性能参数之间的数量关系式。利用这些关系式评定了铝合金焊接接头各区的力学性能,微型剪切试验为铝合金焊接接头力学性能的评定提供了一个新途径。The characteristic values of micro shear test and tensile test of alloy aluminium were determined and the quantitative expressions of these characteristic values were studied.The mechanical properties in different area of weld joints of alloy aluminium could exactly evaluated by these expressions.The micro shear test could give a new way to evaluate on the mechanical properties in weld joints of alloy aluminium.

关 键 词：铝合金 微型剪切试验 拉伸试验 焊接接头
