以高纯钨粉为原料,采用粉末冶金,旋压加工方法,研究了制坯和变形工艺同钨管密度、组织、机械性能、再结晶温度及加工性能的关系,突破了烧结、旋压、表面精整、磨加工等一系列技术难关,研制成功无缝薄壁钨管。其工艺路线和产品性能达到国内先进水平。 钨管的加工变形量在70％以上,密度>19.0克/厘米~3,维氏硬度>450,开始再结晶
High-purity tungsten powder as raw material, using powder metallurgy, spinning process, the billet and deformation process with tungsten tube density, microstructure, mechanical properties, recrystallization temperature and processing properties, breaking the sintering, spinning, Surface finishing, grinding and a series of technical difficulties, the successful development of seamless thin-walled tungsten tube. Its process route and product performance have reached the advanced domestic level. Tungsten tube processing deformation in more than 70%, density> 19.0 g / cm ~ 3, Vickers hardness> 450, began to recrystallize
