Max phases are new generation of advanced materials which their fabrication method, structure and properties have been investigated more in recent years. These types of materials have many different structures which one of the important is based on Titanium, Aluminum and Carbon elements. In thisstudy Ti2AlC and Ti3AlC2 max phases were synthesized using an alternative route called Mechanically Activated Self-propagating High temperature Synthesis (MASHS). This process was performed by combination of short duration ball milling (MA) of reactants (Ti, Al and C as raw materials) and selfpropagating high temperature synthesis (SHS). Mixtures of Ti/Al/C by mole ratio of 2:1:1 and 3:1:2 were milled for 2h., then reacted in microwave or high temperature furnace and their reaction behavior and structure have been investigated by DTA and XRD. Results revealed that it’s possible to fabricate thesematerials by MASHS method but purity of them depends on type of reaction condition. DTA and XRD analyses proved that increasing of soaking time did not improve purity of compounds and some impurities such as TiC would be formed in non optimized reaction routes.
