Hot deformation behavior of mechanically alloyed Al6063/0.75Al2O3/0.75Y2O3 nano-composite-A study using constitutive modeling and processing map

► Flow stress behavior of the MA'ed Al6063 based nano-composite was studied. ► Constitutive model has been developed for the prediction of flow stress. ► Hot workability is interpreted by processing maps based on DMM. ► Provide useful guidelines for the optimization of processing parameters. ► Flow instability regions identified and the mechanism was evaluated.
