Title: Joining of rapidly solidified powder metallurgy Al-Fe-Ce alloys

Journal Article · · SAMPE Q.; (United States)
OSTI ID:6001439

Joining of rapidly-solidified powder metallurgy (RS/PM) Al-Fe-Ce alloys by capacitor-discharge and inertia-friction welding investigated from a metallurgical perspective. Capacitor-discharge welding was effective in the joining of 6.4 mm diameter Al-8Fe-4Ce rod. The application of pressure simultaneously with fusion zone solidification suppressed the formation of fusion zone porosity in this high-hydrogen PM product. In addition, extremely rapid cooling rates promoted RS fusion zone microstructures and prevented heat-affected zone (HAZ) formation, thereby providing joint efficiencies up to 100%. 4 references, 9 figures, 2 tables.
