摘要：

The Electro-Thermal Explosion under Pressure with Confinement (ETEPC) mode of SHS has been studied for producing possibly low-porosity Ti2AlC and Ti3AlC2 from elemental powders in a very short processing time. The effect of maintaining the electric current after the ignition of exothermic reaction has also been studied. A better achievement of the desired reaction, with a total yield of MAX phases up to 73%, was obtained with maintaining the electric current for 4 s after ignition of the exothermic reaction in the Ti : Al : C = 2 : 1 : 1 composition. XRD studies revealed also composition gradients.
