Studies of Metal-Ceramic Reactions in High Strength Steel Cast Alloys

摘要

Experimental studies were made of reactions of mold refractory and crucible refractories with molten metal at the metal-refractory interface. Iron and iron-chromium alloys were studied in the solid and liquid state in contact with silica and stabilized zirconia refractory materials. Preliminary studies indicated the beneficial effect of chromium additions to iron in minimizing interface reaction. Based on these preliminary studies, phase equilibria and kinetic experiments were performed. Light microscopy, electron microprobe analysis, quantitative x-ray diffraction and dilatometric analyses were performed on the resulting specimens.
