ABSTRACT:
A rivet is formed from a friction-actuated extrustion. The extrusion is produced by a process that utilizes a comminuted rapidly solidified aluminum alloy ribbon as the in-feed for a continuous friction-actuated extruder. Gumming and flow problems are eliminated. The extruded product is devoid of surface blistering. The extrusion is converted into a rivet that has improved ambient and elevated temperature mechanical properties.
