Machine Casting of Ferrous Alloys
Abstract
The initial aim of the overall program was to plan and test new and innovative processes and develop a machine casting system for ferrous alloys that would produce good quality parts economically and at high speed. Emphasis of the work at the University of Illinois was on processes and casting systems which employ a partially solid alloy as charge material. The program was especially designed to establish the processing conditions necessary to produce porosity-free parts and to evaluate the Rheocasting and Thixocasting processes from both a technical and economical point of view. Analytical and computer models were developed for solutionizing of Rheocast and conventional cast (dendritic) alloys. The predictions were compared with experiment on a model alloy system, 2024 aluminum base alloy. Recent results of die life studies obtained from M.I.T. were incorporated in the cost analysis model developed earlier and a cost per piece for a previously investment cast part was calculated for manufacture via the new machine casting process. This final report summarizes earlier results reported in the first eighteen months of the program and covers the details of the last 12 months.
