The recycling of metals by plastic deformation: an example of recycling of aluminium and its alloys chips

摘要: Abstract In this paper a new method of recycling aluminium and aluminium-alloy chips coming from the machining semi-finished products, which are very difficult to recycle by conventional methods, is presented. The consists in conversion directly (without melting processes) into finished product. Using powder metallurgy technique followed extrusion, has been applied production composite materials, characterised good properties. environmentally friendly gives saving material, labour energy.
