Al–Si–Mg alloys are increasingly employed in high-pressure die casting (HPDC) automotive structural components due to their lightweight potential and recyclability. This study investigates the fatigue behavior and fracture mechanisms of a 75 pct recycled AlSi10MnMg alloy, using specimens directly extracted from an industrial HPDC automotive component. Specimens retaining the original as-cast surface were subjected to three different heat treatment conditions: E-coating simulation (EC), artificial aging (AA), and annealing (AN). Microstructural characterization, nanoindentation mapping, and high-cycle fatigue tests were combined with fractographic analysis to correlate microstructural features with fatigue crack nucleation and propagation mechanisms. The results revealed a heterogeneous cross-sectional microstructure, generating a hardness gradient that significantly influenced fatigue behavior. Among the investigated conditions, AA provided the highest fatigue strength (138 ± 4 MPa), while EC and AN showed lower performance. Fractographic observations revealed that fatigue crack nucleation was associated with the local discontinuity of the skin layer, whereas crack propagation was mainly governed by the hardness distribution induced by heat treatment. The environmental impact assessment indicated that, despite its additional processing energy, AA reduces the overall life-cycle environmental burden by extending component lifetime.
