Abstract
A Sciaky electron beam additive manufacturing (EBAMâ¢) system was used to deposit low-carbon arc-cast (LCAC) and powder metallurgy (PM) Mo onto corresponding substrates. Results show dramatic differences in the quality of the two deposited materials. LCAC deposits were crack-free with low porosity while the PM material contained gross porosity and cracks. Analytical data highlighted that the difference in deposition behavior can be attributed to differences in the concentration of volatile elements such as Ca, Na and low boiling point oxides present in the starting materials.
