Hey Suraj, By allowing precipitation to occur at much below the solvous line, precipitation at grain boundaries can be avoided. At this temperature nucleation at grain boundary is not easy because at this temperature atoms cannot move to the grain boundary (diffusion rates are not high). So, the preRead more
