Bauxite residue (BR) is an industrial by-product generated during the production of alumina from bauxite ores in Bayer process. BR environmentally hostile due to it high alkalinity and fine particle size distribution. In this work, blended with NaOH subsequently reduced hydrogen, order develop intermediate material rich magnetite sodium aluminate, by doing so, enable recovery iron, aluminium as...

In a recent article [J. Rajagopalan, J.H. Han, M.T.A. Saif, Science 315 (2007) 1831–1834], we have reported substantial (50–100%) plastic strain recovery in freestanding nanocrystalline metal films (grain size 50–65 nm) after unloading. The strain recovery was time dependent and thermally activated. Here we model the time evolution of this strain recovery in terms of a thermally activated dislo...

In achieving accurate results, current nonlinear elastic recovery applications of finite element (FE) analysis have become more complicated for sheet metal springback prediction. In this paper, an artificial neural network (ANN) was used to mimic the nonlinear elastic recovery and provides a generalized solution in the FE analysis. The nonlinear elastic recovery was processed through back-propa...
