Steel pipe lined Fe-Al intermetallic-TiB2-Al2O3composite were prepared by centrifugal-self-propagating high temperature synthesis (centrifugal-SHS) process from FeTiO3, B2O3, Fe2O3, Al and CaF2as raw materials. The standard Gibbs energy minimization method was used to calculate the equilibrium compositions of the reacting species. The effect of adding CaF2to the precursors on the result product were investigated. The phase separation between less porosity Fe-Al intermetallics-TiB2with Al2O3layer were affected greatly by adding CaF2. The phase compositions and morphology were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) couple with energy dispersive X-ray (EDX), respectively.
