Effect of powder size on Ti-6Al-4V alloy sintered by hot isostatic pressing below beta transus temperature
Source abstract
Abstract
• Microstructural and mechanical properties of Ti-6Al-4 V capsule HIPed powders with different sizes were characterized. • Ti-6Al-4 V capsule HIPed below β-transus temperature exhibited a unique microstructure and improved strength. • Oxygen solution and hardening effects varied with particle size, significantly influencing mechanical properties. This study investigates the effect of Ti-6Al-4 V powder particle size on relationship between microstructure and mechanical properties after sintering via hot isostatic pressing (HIP) below the β-transus temperature with three type of powder size distribution. As particle size was smaller, the strengthening effect was induced by solid solution of oxygen and precipitation of nano-sized β phase. Thus, in the view of particle size this study proposes the strengthening mechanisms during HIP treatment of Ti-6Al-4 V.
