Significant improvement of semi-solid microstructure and mechanical properties of A356 alloy by ARB process

▶ ARB process was used as a new effective technique was performed on A356 alloy. ▶ Increasing the number of cycles improved the uniformity of silicon particles. ▶ When the number of cycles increased, the hardness improved. ▶ The tensile strength of the samples improved, when the number of cycle increased. ▶ When the number of cycles increased, first elongation decreased and then, rose.
