This research studies a hybrid method of manufacturing of porous alloy/ foam or functionally graded porous alloys with the help of a hybrid process of friction stir processing followed by microwave post-processing. The manufacturing productivity of such porous alloys is enhanced due to the robust and fast processing times of FSP, and the rapid and selective heating of microwave heating. Thus, this hybrid process decreases the time of manufacturing and improves productivity drastically in comparison to the casting and normal powder metallurgy route. Aluminium alloy plates of thickness 5 mm is taken and grooves of 2 mm depth and 1.5 mm width are milled along the aluminium alloy plate and filled with TiH₂ powder.
