    Statistical analysis of SiC addition on heterogeneous nucleation of $\alpha-Mg$ primary phase in the AZ91/SiC composite
    (2010) Gracz, Beata; Lelito, Janusz; Żak, Paweł; Krajewski, Witold; Suchy, Józef Szczepan; Szucki, Michał
    The aim of this research was to compare influence of different SiC mass fraction and different SiC particle size on the nucleation process of magnesium primary phase in AZ91/SiC composite. This paper presents experimental results using SiC particles as a reinforcement for AZ91 alloy and their influence on both the grain size of $\alpha-Mg$ primary phase and dimensional homogeneity of grains of this phase. This study provides a good basis for optimizing the process of preparing the AZ91/SiC composite.
