从厦门虹鹭钨业有限公司提供的烧结纯钨坯料、17%、60%和80%轧制板坯中，分别切取10*10*10mm尺寸的金相试样，并对样品进行精密机械抛光。通过阿基米德排水法测试样品的实际密度，用实际密度除以理论密度，获得样品的相对致密度变化。并借助Origin绘图软件绘制出不同变形量下纯钨样品的致密度变化曲线。

From the sintered pure tungsten blanks, 17%, 60%, and 80% rolled slabs provided by Xiamen Honglu Tungsten Industry Co., Ltd., metallographic samples of 10*10*10mm size were respectively cut, and the samples were subjected to precision mechanical polishing . The actual density of the sample is tested by Archimedes drainage method, and the actual density is divided by the theoretical density to obtain the relative density change of the sample. And draw the density change curve of pure tungsten sample under different deformation amount with the aid of Origin drawing software.
