Reactive Sintering Mechanism and Phase Formation in Ni-Ti-Al Powder Mixture During Heating

Original language description

This work aims to describe the formation of intermetallics in the Ni-Ti-Al systemin dependence on the heating rate, which has been determined previously as the crucial factor of thermal explosion self-propagating synthesis (TE-SHS). The tested alloys contained 1-7 wt % aluminum. Thermal analysis has been realized by the optical pyrometer under the conditions of high heating rates up to 110 degrees C.min(-1). TE-SHS process in Ni-Ti-Al system is initiated by exothermic reaction of nickel aluminides Ni2Al3 and NiAl3 at the temperature of 535-610 degrees C. The next reactions occur in dependence on the heating rate. Samples containing 1-3 wt % of aluminum exhibit the similar initiation temperature as Ni-Ti binary mixture. The samples containing 5 wt % and more of aluminum were fully reacted after sintering at 800 degrees C with the heating rate of 300 degrees C.min(-1) and the initiation temperature of the TE-SHS was observed close to Al-Al3Ni eutectic temperature (between 630-640 degrees C).
