Tungsten metal material tensile sample

The utility model belongs to the technical field of tungsten metal material performance testing, and particularly relates to a tungsten metal material tensile sample. The tensile sample comprises a straight section, a transition section and a clamping section, the clamping section comprises a clamping core layer and a clamping stress layer, and the clamping stress layer is cladded on the clamping core layer. When the tungsten metal material tensile sample is subjected to a tensile test, the clamp of the test tool is clamped on the clamping stress layer of the clamping section, the pressure applied by the chuck of the clamp is dispersed through the clamping stress layer, and the clamp is not in direct contact with the clamping core layer of the clamping section, so that the tensile sample is prevented from forming tensile stress concentration on the clamping core layer, and the tensile test efficiency is improved. Therefore, the tungsten metal tensile sample is prevented from being broken at the clamping secti
