ISSI-2: Tuesday's Contributed Presentations

September 21-25, 1997 · Champion, Pennsylvania

ISSI-2 Logo The 2nd International Symposium on Structural Intermetallics (ISSI-2), sponsored by the High Temperature Alloys and Titanium Committees of The Minerals, Metals & Materials Society's (TMS's) Structural Materials Division will be held at the Seven Springs Mountain Resort, Champion, Pennsylvania, Sunday, September 21, through Thursday, September 25, 1997. The following presentations represent the contributed papers that will be held during Tuesday morning's Microstructure & Properties session and Tuesday afternoon's Ni3Al and Iron Aluminides session. These presentations will be complemented by a collection of invited papers. See the calendar of events for more information.
