Cast aluminium-silicon alloys have been found attractive over ferrous alloys for applications in automotive pistons. As a result, production of piston components from cast aluminium-silicon alloys has increased, which, in turn, has led to increase in volume of scrap of these alloys. Consequently, there is concerted effort in research to develop effective procedures of recycling. As part of this effort, this book provides an investigation of the microstructure and microhardness evolution of recycled cast aluminium-silicon piston alloys processed by high-pressure torsion (HPT). It is an attempt...
