If I do the ball milling of Ni50Mn45Sn5 (atomic %) for 20 hours in presence of Toluene as process controlling agent. Argon flow and vacuum were not maintained during milling.
(i) Will the outcome alloy be a single phase or not?
(ii) What phase (Austenite or Martensite) will form just after the ball milling?
(iii) If I want to go for magnetic measurements, Do I need to anneal it first? else I can go for magnetic measurements without annealing?
(iv) If annealing is necessary then what should be the annealing temperature and time?
I don't know about the resulting material, but annealing wil probably change the structure and the magnetic properties. Xrays, and magnetic measurements must be performed just after "ball milling" before and after annealings at various temperatures.
Looking at the composition of the material (as a first approximation a Ni-Mn alloy) one would get some insight from the Ni-Mn phase diagram, and information on the possible occurrence of non-stable phases and phase transitions. The ASM compilation of binary phase diagrams might be a useful start point...
