Processing Aluminum Scrap Vial Mechanical Alloying and Subsequently Hot Extrusion

Abstract:

Recycle aluminum cans, an alternative route is presented in this work. The aluminum cans are cut in little flakes with a shears, and then the materials were milled, obtained fine powders. The weight ratio of the balls to powder was 10 to 1. Equipment of a horizontal high energy ball mill was utilized. The powder mixture was processed during 0.5, 1 and 2 hours at 950 rpm and after milling, the powders were directly hot extrusion. The extruder bars were submitted at a tensile tests and samples microstructures were analyzed by optical microscope. Experimental results obtained shows that the technique utilized in this work is very important for economized routes and consequently, less expensive, as compared with conventional methods.
