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φ8×12mm的试样，表面打磨光亮，然后进行轧制过程的热物理模拟实验。在Gleeble-3800热物理模拟机实验平台，进行1300-1500℃温度，0.1-0.0001s^-1应变速率的等温热压缩实验，采集获得高温应力-应变数据；借助Origin绘图软件，绘制出不同温度和应变速率条件下纯钨烧结样品的等温应力-应变曲线。

From the hydrogen furnace sintered pure tungsten blank provided by Xiamen Honglu Tungsten Industry Co., Ltd., a sample with a size of φ8×12mm was cut, the surface was polished and bright, and then the thermal physical simulation experiment of the rolling process was carried out. On the experimental platform of the Gleeble-3800 thermal physics simulator, perform isothermal thermal compression experiments at a temperature of 1300-1500℃ and a strain rate of 0.1-0.0001s-1 to collect high-temperature stress-strain data; use Origin drawing software to plot different temperatures The isothermal stress-strain curve of pure tungsten sintered sample under the condition of and strain rate.
