Abstract
A metal alloy workpiece is heated convectively in a first step by heat conduction, heat radiation or further non-inductive heat transfer to a temperature lying just below the solidus temperature of the alloy and is heated inductively in a subsequent second step to the final temperature lying between solidus and liquidus temperature. The process is particularly suitable for producing workpieces having thixotropic properties intended for further processing, in particular for further processing bolts or bars in die-casting, forging, rolling and pressing plants.
