A STUDY OF THE EFFECT OF ELECTRON BEAM MELTING ON COMPOUNDS AND METALS
REACTIVE METALS INC NILES OHIO
Pagination or Media Count:
A study was made of the effect of the electron beam melting process on B, B-C alloys, B-Si alloys, TaC, TiC, ZrB2, Hf, W, Co, V, and Be. In addition, deoxidation studies were carried out on Be, V, Co and Mo. When possible, microstructures, tensile properties, and chemical compositions of the materials melted were obtained. The compounds studied either could not be melted or were brittle after melting. The interstitial content of all the metals was reduced by the electron beam melting process. By the addition of deoxidants, the interstitial contents of Mo and Be were reduced. Improvement in the tensile properties of V and Mo were obtained by the addition of deoxidants. Author
