PROCESS AND APPARATUS FOR PROVIDING IMPROVED SLURRY CAST STRUCTURES BY HOT WORKING

摘要

A process and apparatus for providing metal material having an improved structure for forming into a desired article is disclosed herein. The improved structure is obtained by slurry casting a material into a continuous member and then hot working the slurry cast material. Upon reheating to a semi-solid state, the hot worked, slurry cast material will exhibit finer particles and fewer eutectic melting rosettes than would be exhibited by the slurry as-cast material in an unworked and heated condition. The hot working of the slurry cast material produces an article having a deformed structure exhibiting directionality.
