通过接头剥离和拉伸-剪切试验研究了铝锂合金(1420)和钛合金(TA1)同种异种压印T型和单搭接头的力学性能。由试验结果比较可知,低强度下板压印接头的承载能力较高,低强度下板在两种接头的能量吸收值均高于高强度下板。
The mechanical properties of Al-Li alloy (1420) and titanium alloy (TA1) allogenic imprinted T-type and single-lap joints were investigated by means of peel-off and tensile-shear tests. According to the comparison of the test results, the bearing capacity of the low-strength under-plate stamping joint is higher, and the energy absorption values of the lower joint under the low-strength plate are higher than that of the high-strength lower plate.
