Material low-temperature test target piece

The invention provides a material low-temperature test target piece which comprises a shell, a plurality of test units and a plurality of first heat conduction assemblies. A containing cavity is formed in the shell, and the containing cavity extends in the axial direction of the shell; the plurality of test units are arranged in the accommodating cavity at intervals along the axial direction of the shell; and each first heat conduction assembly is connected between two adjacent test units and is used for realizing temperature axial flattening among the plurality of test units. According to the technical scheme, axial temperature flattening of the material sample in the material low-temperature test target piece can be achieved. 本发明提出一种材料低温试验靶件，包括外壳、若干试验单元以及若干第一导热组件；所述外壳内形成有容置腔，所述容置腔沿所述外壳的轴向延伸设置；若干所述试验单元沿所述外壳的轴向间隔设置于所述容置腔内；每一所述第一导热组件连接于相邻两所述试验单元之间，用于实现若干所述试验单元间的温度轴向展平。本申请的技术方案，能够实现材料低温试验靶件内材料样品的轴向温度展平。
