氢处理是能够使钛合金晶粒尺寸达1μm以下的为数较少的方法之一。利用这种方法可以使α+β型钛合金Ti-6Al-4V及富β的α+β型钛合金Ti-4.5Al-3V-2Mo-2Fe获得晶粒尺寸小于0.5μm的等轴细晶组织,使合金具有优异的超塑性能。日本学者中東潤对这两种合金进行氢处理,研究其常温性能及超
Hydrogen treatment is one of the few ways to make the titanium alloy grain size less than 1 μm. Using this method, an equiaxed fine crystalline structure with grain size less than 0.5 μm can be obtained for the α + β titanium alloy Ti-6Al-4V and β-rich α + β titanium alloy Ti-4.5Al-3V-2Mo-2Fe , The alloy has excellent superplastic performance. Japanese scholar Middle East Run hydrogen treatment of these two alloys to study its room temperature properties and ultra
