摘要	A Ti-22Al-24Nb-0.5Mo (at%) pre-alloyed powder was produced by gas atomization, and then fully dense powder metallurgy (PM) Ti2AlNb alloy was fabricated by a hot isostatic pressing (HIPing) route. powder size distribution obviously affects the porosity distribution of PM Ti2AlNb alloys. The weld porosity and inclusion are not found in the as-HIPed+HT Ti2AlNb rings to be electron beam welded according to the X-ray radiographic inspection. The microstructure of as-HIPed+HT Ti2AlNb compacts was characterized by optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). From the fusion zone to the parent material, the microstructures change from the single phase (B2) to duplex (alpha(2)+B2+O phase). The microhardness of fusion zone and heat affected zone is higher than that of parent material.
