Machine Casting of Ferrous Alloys

Abstract

This final report of a three-year program contains some highlights of the earlier reports and much detail about Rheocasting and the casting of aluminum containing superalloys by Hitchiner's patented CLA process. Aluminum castings were made using metal up to about 25% solid and steel castings using 10% solid metal were also made. No improvement in casting quality was noted in either case. GMR 235 and Inco-713LC alloys cast by CLA showed excellent properties. Some of these turbine wheels submitted to a major turbocharger manufacturer passed the qualification test. Low pressure reusable mold processes for casting ferrous alloys were not economical because of inadequate die life and hot tearing of the castings.
