Abstract

High quality Ti–6Al–4V alloy powders were prepared by plasma rotating electrode process (PREP). Three different rotating speed were selected. After sieved, three kinds of powder with different size distribution were consolidated by hot isostatic pressing (HIP). The phase compositions, morphologies and microstructures of the powders and HIPed samples were characterized. Mechanical properties of HIPed Ti–6Al–4V alloys also were investigated. The results showed that the proportion of small particles increased with the increasing rotating speed. Alloy prepared by powders distributed in 100–150 μm possesses the best mechanical properties.
