SINGLE PIECE CASTING OF REACTIVE ALLOYS

摘要

A method of vacuum induction melting a charge of material includes preheating a mold; inserting the charge into the mold; placing the mold into a chamber; reducing an operating pressure within the chamber; induction melting the charge within the mold; allowing material of the charge to fill a cavity defined within the mold; applying electromagnetic pressure to the charge within the mold; and applying an electromagnetic field to material of the charge positioned within the cavity defined within the mold.
