High-pressure diecasting of ferrous and other high melting range alloys

Abstract

An outline is given of the major features of a new process, known as ‘Ferro-Di’, developed for the high-pressure diecasting of ferrous and other high melting range alloys. Details are given of the structures and representative mechanical properties of components cast at the very high cooling rate that is an inherent feature of the high-temperature diecasting process. The effect of melting technique on product composition is also discussed. Components in current production and some components under development are described, with emphasis on the structures of the products. Materials diecast so far by the Ferro-Di process include mild and low-alloy steels, a range o/stainless steels, and some nickel- and cobalt-based alloys.
