Resum
A novel method was developed, based on thixotropic nature of semi-solid slurry of aluminum silicon alloy, for the effective dispersion and distribution of short carbon fibers (Csf) under intensive shear stress (t) into the eutectic without physical or chemical damage. The Csf were distributed homogeneously into the matrix at optimum conditions: a temperature of 576–580 °C, around 48% of solid fraction, and rotation speed of mixing was at 100 rpm. The gas entrapment and porosity was a challeng...
