I mean, I took an alloy of very low quantity (2gm) and after heat treatment I could get single phase, now I have taken the same composition but slightly higher weight (15 g). Is it advisable to keep the annealing time and other parameters the same or they should be changed?
Syed Zameer Abbas
Sample size/dimensions may effect the results of heattreatment. It depends upon the type of alloy and the dimensions of the section. Also to get repeatable results the composition should be the same without any segreggation. Increasing the annealing time may help but longer annealing time can also lead to grain coarsening. Parameters should be the same if that is possible otherwise one has to adjust accordingly. Consult the phase diagram, it will be helpful.
