Influence of heat treatment on fatigue behaviour of high-strength Mg–10Gd–3Y alloy

The current work investigated the influence of heat treatment (T4, T5 and T6) on high cycle fatigue (HCF) behaviour of the as-extruded Mg–10Gd–3Y (GW103, wt.%) alloy. The five heat treatment conditions applied to the as-extruded GW103 alloy were under-aging (T5, 225 °C × 4 h), peak-aging (T5, 225 °C...
