研制了温温式双轴拉伸试验仪。该装置可以同时实现应力比和应变率的控制，因为为了准确测量等塑性功轨迹，必须保持这些参数。对厚度为1 mm的AA5182-O铝合金板材进行了温差双向拉伸试验。结果表明，等塑性功轨迹的形状对温度没有很强的依赖性。
Warm temperature biaxial tension test apparatus was developed in this study. This device can achieve stress ratio and strain rate controls simultaneously because it is necessary to keep those parameters for an accurate measurement of equi-plastic work locus. The warm temperature biaxial tension tests were conducted on AA5182-O aluminium alloy sheet with the thickness of 1mm. The obtained results showed that the shapes of equi-plastic work loci did not have strong temperature dependency.
