The crystallite size decreased with an increase in percentage rolling while the lattice strain had the opposite effect. XRD pattern has clearly indicated the Al and Si peaks. The 60% cold rolled specimen showed a 35 and 142% increase in hardness as compared to as-built and as-cast alloy respectively. However, the increase in hardness upon increasing the percentage reduction in thickness is mainly attributed to the phenomenon of dislocation strengthening. There was not much difference in the size of the aluminum cells and Si particles with respect to the percentage rolling reductions or on the other hand rolling has not brought any change in the microstructural morphology. Solution heat treatment has resulted in the formation of discrete Si particles in the matrix. Scanning electron microstructure of the as-built sample revealed the silicon network surrounding the alpha aluminum cells. The optical microstructure of the as-built sample revealed the melt pool boundaries on the surface and fish scale morphology in the transverse plane. The density of the as-built, solution treated, and cold-rolled samples was measured using Archimedes’ principle. Optical, scanning electron microscope and XRD were used for characterization. The current work aims at assessing the effect of cold cross-rolling on the microstructure and hardness. Samples were rotated by 90° between the passes. Solution-treated samples were cold rolled to 20, 40 and 60% reduction with multi-passes. AlSi10Mg alloy of 80 × 25 × 5 mm rectangular pieces was manufactured using a laser-assisted powder bed fusion route and subsequently solutionized at 520 ☌ for 2 hours. Properties such as corrosion resistance, low density and high specific strength open the door to be a competitive material in aerospace and automotive industries. AlSi10Mg is the most widely processed material among the Al-Si-Mg family by utilizing additive manufacturing routes.
