Second semi-solid processing, also plays an important role in.The uniform distribution of the SiC particles in the preform sample.In fact it is, believed that creation of a vortex in the semi-solid stirring.Process breaks solid dendrites at 605 C because of higher friction.Between the SiC particles and the aluminium alloy matrix.This further induces a homogeneous distribution of the SiC particles.In the matrix of the solidified A356 composite, In addition.The sedimentation of the SiC particles decreases at the semi-solid.State stirring temperature [27], which can also result in a homogeneous.Distribution of the SiC particles because of the presence of a.Solid phase.
