Self-propagating high-temperature synthesis (SHS) of rotator mixed and mechanically alloyed Ni/Al powder compacts

A significant amount of work has been published on the combustion synthesis of nickel aluminides including thermal explosion and SHS type of ignition, [ 1, 2, 3, 4]. In the SHS of nickel aluminides, nickel and aluminum powders are mixed in the desired composition and pressed into a compact, which is then ignited at one end, usually with the aid of a tungsten-heating coil (Fig. 1). An exothermic reaction proceeds converting the nickel and aluminum powders into the desired intermetallic compound, and raises the compact temperature to the maximum combustion temperature.
