Mechanical properties of HIP columbium C-103 alloy

Progress in studying the feasibility of producing near net shape components of Columbium C-103 via powder metallurgy and hot isostatic pressing (HIP) is presented. The effect of powder particle size, shape and purity, and of HIP conditions on the room temperature and 3000/sup 0/F properties and on welding are presented, and the results are explained by microstructural, fractographic and Auger analyses. In general, the HIP product compares favorably with commercial wrought material.
