A promising technology for integration of top-down nanomanufacturing is equal channel angular pressing, a process transforming metallic materials into nanostructured or ultra-fine grained materials with significantly Hoodie enhanced performance characteristics.To bridge the gap between process potential and actual manufacturing output a novel prototype system identified as indexing equal channel angular pressing (IX-ECAP) was developed to capitalize on sustainable engineering opportunities of transforming spent or scrap engineering elements into key engineering commodities by recycling 4043 aluminium alloy welding rod residuals.A resolution III fractional factorial split-plot experiment assessed significance of predictors on the response, microhardness, with multiple linear regression used for model development.

Five process parameters involving pressing temperature, number of passes, pressing speed, back pressure, and vibration were Pre-Rolled studied.Microhardness conversions allowed theoretical determination of grain sizes employing Hall-Petch relationships.IX-ECAP offered a viable solution whereby processing of discrete variable length work pieces proved very successful.
