Preparation of an Al–Ti–Mg Composite by Self-Propagating High-Temperature Synthesis

— A lightweight intermetallic alloy containing the ternary phase Al 18 Ti 2 Mg 3 has been prepared for the first time in the Ti–Al–Mg system by self-propagating high-temperature synthesis. In the binary system Ti–Al, synthesis has been carried out in the thermal explosion regime, whereas in the ternary system Ti–Al–Mg layer-by-layer combustion synthesis has been performed. The porosity of the synthesized materials is 43.3%, and its density is 2.4 g/cm 3 .
