Detailed insight into the thermal explosion synthesis (TES) of a TiC/Mg composite has been gained by the authors. SEM microstructures and XRD patterns of TiC/AZ91D obtained by TES synthesis from Mg and Al‐Ti‐C preforms reveal that the temperature of the molten Mg greatly influences the incubation time for the TES reaction and the reaction product. Thus, TiAl 3 clusters present at a reaction temperature of 700 °C (see Figure) disappear when the reaction is performed at 900 °C.
