Failures analysis of in-situ Al–Mg2Si composites using actual microstructure based model

In-situ Al–Mg2Si composites (0, 5, 10, 15, 20 wt% Mg2Si) were synthesized in an Al–Mg–Si system through gravity casting route. Influences of the Mg2Si addition (in terms of Mg and Si) on the mechanical properties, microstructural morphology, fracture behaviors, micro-mechanical response and failure initiation were systematically studied through experiments and mathematical modeling. Experimental results show that the primary Mg2Si formed in...
