Abstract
A method for hearthless processing of a solid metallic material consisting essentially of titanium or other metal or alloy thereof which includes providing a solid metal block having a processing surface and a base surface and consisting essentially of titanium or a metal, forming a pool of molten metal on the processing surface of the solid metal block provided in step, adding the metallic material to be processed to the pool of molten metal formed in step, and melting the metallic material to be processed, and removing metallic material melted in step from the pool of molten metal.
Claims77
