Abstract: An apparatus for melting an electrically conductive metallic material includes a vacuum chamber and a hearth disposed in the vacuum chamber. At least one wire-discharge ion plasma electron emitter is disposed in or adjacent the vacuum chamber and is positioned to direct a wide-area field of electrons into the vacuum chamber, wherein the wide-area electron field has sufficient energy to heat the electrically conductive metallic material to its melting temperature. The apparatus may further include, at least one of a mold and an atomizing apparatus which is in communication with the vacuum chamber and is positioned to receive molten material from the hearth. Preferably, the pressure within the furnace chamber is maintained at more than 5,3 Pa to decrease evaporation of volatile elements.

Abstract: Methods of refining the grain size of titanium and titanium alloys include thermally managed high strain rate multi-axis forging. A high strain rate adiabatically heats an internal region of the workpiece during forging, and a thermal management system is used to heat an external surface region to the workpiece forging temperature, while the internal region is allowed to cool to the workpiece forging temperature. A further method includes multiple upset and draw forging titanium or a titanium alloy using a strain rate less than is used in conventional open die forging of titanium and titanium alloys. Incremental workpiece rotation and draw forging causes severe plastic deformation and grain refinement in the titanium or titanium alloy forging.

Abstract: A method of processing a metal alloy includes heating to a temperature in a working temperature range from a recrystallization temperature of the metal alloy to a temperature less than an incipient melting temperature of the metal alloy, and working the alloy. At least a surface region is heated to a temperature in the working temperature range. The surface region is maintained within the working temperature range for a period of time to recrystallize the surface region of the metal alloy, and the alloy is cooled so as to minimize grain growth. In embodiments including superaustenitic and austenitic stainless steel alloys, process temperatures and times are selected to avoid precipitation of deleterious intermetallic sigma-phase. A hot worked superaustenitic stainless steel alloy having equiaxed grains throughout the alloy is also disclosed.
