从厦门虹鹭钨业有限公司提供的氢气炉烧结纯钨坯料中切取尺寸为φ8×12 mm的试样，表面打磨光亮，然后进行热物理模拟轧制实验。在Gleeble-3800热物理模拟机实验平台，进行1300-1500℃温度、0.1-0.0001s-1应变速率、30%和60%变形量的等温热压缩实验。将等温轧制样品沿着轴向剖分，按照标准的金相制样流程制备出金相试样。在扫描电镜上观察样品内部的孔洞分布，并拍摄SEM照片。借助Image Tool软件统计分析样品的致密度。借助Origin绘图软件绘制出不同热物理模拟纯钨样品的致密度变化曲线。

A sample with a size of φ8×12 mm was cut from a pure tungsten blank sintered in a hydrogen furnace provided by Xiamen Honglu Tungsten Industry Co., Ltd., the surface was polished and bright, and then a thermophysical simulation rolling experiment was carried out. On the experimental platform of the Gleeble-3800 thermal physics simulator, isothermal thermal compression experiments with a temperature of 1300-1500°C, a strain rate of 0.1-0.0001s-1, and a deformation amount of 30% and 60% were carried out. The isothermally rolled sample is divided along the axial direction, and the metallographic sample is prepared according to the standard metallographic sample preparation process. Observe the distribution of holes inside the sample on a scanning electron microscope, and take SEM pictures. Analyze the density of the samples statistically with the help of Image Tool software. With the aid of Origin drawing software, the density change curves of different thermal physics simulation pure tungsten samples are drawn.
