摘要: Abstract–Combustion synthesis of the Ni,AI intcrmetallic was studied using self-propagating hightemperature (SHS) mode. Since reaction wave propagates rather quickly through sample in SHS, a successful application this process requires an understanding influence processing variables on its dynamics, and phase composition microstructure product. Thus, effects green density, ignition power, preheating temperature, particle sizes aluminum nickel were investigated. In addition, particles with different morphology used. It found that higher lower power temperature lead to fully reacted product well-developed microstructure. The reactant their also significantly properties. obtained results arc helpful mechanism for mation Ni3Al.
