Abstract
Friction Stir Extrusion is a new energy-efficient solid-state material processing for alloy synthesizing and metal recycling. In the process, material (metal chips and/or powder) are tightly packed into a cylindrical cartridge which is mounted on a spinning machine; then a metal plunger is inserted and pressed into the rotating cartridge. The heat generated by friction and extensive plastic deformation softens the material, consolidates, and extrudes the materials into alloy wires. Aluminum will be the first material to be extruded, but this process could be utilized to form new materials and alloys as well.
This economic and environmentally friendly material synthesis technology has the following three advantages verse traditionally methods: a) suitable for synthesis of high performance nano-structured materials and advanced materials, b) providing highly energy efficient solid-state solidification method, c) recycling material with much less energy consumption.
Currently, the cartridge and plunger as well as an adaption piece have been designed and manufactured. The plunger has been remanufactured once and the cartridge is currently being remanufactured. One trial was successful in producing aluminum wiring. Microstructure analysis is currently underway in attempt to find the grain size of the aluminum that had not been extruded, but condensed into the bottom of the cartridge.
Future goals in this experiment are to extrude more wire as well as find the microstructure of the aluminum.
