Abstract
Processes and methods related to producing, processing, and hot working alloy ingots are disclosed. An alloy ingot is formed including an inner ingot core and an outer layer metallurgically bonded to the inner ingot core. The processes and methods are characterized by a reduction in the incidence of surface cracking of the alloy ingot during hot working.
Claims16
A process for forming an alloy ingot comprising:
- positioning an alloy liner in a crucible of a vacuum arc remelting apparatus;
- and
- vacuum arc remelting an alloy electrode into the alloy liner in the crucible, thereby forming an alloy ingot comprising an outer layer metallurgically bonded to an inner ingot core.
