A powder alloy of the composition 9wt.% Al, 3wt.% Ni and 88wt.% Mg will be subjected to a sintering process in Argon atm

[answerhappygod]

A powder alloy of the composition 9wt.% Al, 3wt.% Ni and 88wt.%
Mg will be subjected to a sintering process in Argon atmosphere, in
610 degrees Celsius for 120 minutes and a heating rate of 5 degrees
Celsius/minutes. Calculate the Gibbs free energy of the system
(which reaction is favorable, because we do not want brittle phases
like Ni-Al which is a very stable phase but brittle so we do not
want this phase, and other brittle phases because afterwards we
want to metalwork the material (rolling) so we want it to be still
metallic = ductile). Could we lower the temperature to get a more
ductile result?
