US Patent:
52976157, Mar 29, 1994
Filed:
Jul 17, 1992
Appl. No.:
7/916015
Inventors:
Paul R. Aimone - Muskegon MI
Bart M. Kilinski - Montague MI
Keith D. Ramthun - Montague MI
Assignee:
Howmet Corporation - Greenwich CT
International Classification:
B22C 102
B22C 904
US Classification:
164519
Abstract:
A high melting point and/or low ductility metal or alloy is investment cast in a refractory mold including a facecoat layer and a plurality of back-up layers wherein at least one back-up layer is a relatively weak, sacrificial layer. This latter layer is crushed as necessary as the casting cools below its ductile-to-brittle transition temperature to avoid hot tearing or cracking of the solidified metal or alloy during cooling in the mold.
