Effect of the Temperature of Molten Magnsium on the Thermal Explosion Synthesis Reaction of Al–Ti–C System for Fabricating TiC/Mg Composite

Abstract

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, TiAl3 clusters present at a reaction temperature of 700 °C (see Figure) disappear when the reaction is performed at 900 °C.
