Abstract
In this research, a new method for consolidation of Al-20wr%Si powders using a magnetic pulsed compaction (MPC) was introduced. A wide Range of experimental studies were carried out to characterize the mechanical properties and microstructure of the MPCed materials by means of SEM, TEM and tensile test. It was found that the effective properties like higher strength and full density were achieved while maintaining a fine microstructure. Consolidated bulk by MPC showed higher density without any crack than that of the general process. With increasing the number of MPC compaction, the density and mechanical properties were also greatly improved.
