of the eutectic Si particles in the as-cast Al matrix (Fig. 3(a)). It may be mentioned that some portion of the Si particles are expected to go to solid solution at the solutionizing... treatment (Fig. 4) could be attributed to the reduced cracking tendency in view of the presence of hard spheroidal Si particles that allow them to be retained by the Al matrix in view of suppressed......

As a result, the metal matrix (eutectic Al phase) was forced to adjust itself growth direction or repeatedly nucleate on Si phase to adapt a new epitaxial orientation as fast...]. The three-dimensional morphology of eutectic Si in Al-10%Si alloy modified by 0.025% Sr is shown in Fig. 4 (the sample was deeply etched to remove Al matrix). It was found that the irregular eutectic Si......
