The effect of varying levels of Pr inoculation on the microstructure, granularity, and mechanical properties of an Al-30%Mg2Si composite was studied. When the Pr content was increased to 0.8 wt%, the refinement was ideal. Similarly, the mechanical properties such as Ultimate Tensile Stress (UTS), Breaking Elongation (BE), and Vickers Microhardness (VM) values were improved. The relationship between crystal size and UTS or VM was described using the Hall-Petch relationship. (C) 2017 Elsevier B.V. All rights reserved.
