US Patent:
47410809, May 3, 1988
Filed:
Feb 20, 1987
Appl. No.:
7/017293
Inventors:
Jay M. Larson - Marshall MI
Emory Z. Pankas - Riverdale NE
Charles E. Pennock - Kearney NE
Stephen B. Caird - Belmond IA
Michael A. Allibone - Garner IA

Assignee:
Eaton Corporation - Cleveland OH
International Classification:
B21K 124
US Classification:
291567R
Abstract:
A process for providing an engine valve (2) with varied microstructure grain size is provided. The process includes the steps of: providing a slug (4) of suitable metallic valve composition having a grain size of less than about A. S. T. M. 8; solution heat treating slug (4) to provide a larger grain size and to substantially dissolve carbonitride stringers if present; and forging the solution heat treated slug (4) in a manner that provides a substantially uniformly distributed A. S. T. M. grain size of about 1 to about 7 in a central region beneath the combustion face of head (14) of valve (2) while cold working a seat face (16) on head (14) and extruding the stem (10) of valve (2) such that its microstructure grain size is less than about A. S. T. M. 8.
