Combustion Synthesis Sintering of Ni-Al Powder Alloys

Abstract:

According to the different reaction mode, the combustion synthesis sintering can be divided into two kinds of mode: the self-propagating by heating ignition such as laser (SHS, Self-propagating High-temperature Synthesis) and whole explosion in the vacuum furnace (TE, Thermal Explosion). In this experiment, the Ni-Al powder compact is synthesized completely to nickel aluminides by SHS and TE. The experimental parameters controlling the ignition step such as material parameter and adiabatic temperature were calculated as a function of initial stoichiometry. Al mole ratio in initial powder mixture was varied from Ni: Al=3:1 to Ni: Al=1:1 for controlling adiabatic temperature.
