Hi Mainak,

a higher SFE is not the consequence but the reason for fewer stacking faults. The SFE decreases if the energy difference between the hcp- and fcc-structure in a metal is small.

Other parameters such as particle size and temperature also affect the SFE.

I want a detailed explanation please, which is different from typical textbook explanations!
