Abstract: The criterion to control self-propagation high temperature synthesis for the fabrication of porous Ti-Al intermetallics was established from the prereaction model and the thermal balance condition. The criterion equation reflecting the relation between the solid reaction layer thickness correlation parameter and the ignition temperature was deduced to be p(3)=C(1)/(T(ad)-T(0)) + C(2), according to which the near net shaping synthesis of porous Ti-Al intermetallics was realised, which was significantly important for the industrial productions and applications of this high performance novel porous material. The slight difference between theoretical predictions and experimental data was analysed according to the model analysis.
