Professor Bhadeshia,why the particle is fine before the precipitation cease ?

[@achmadariaseta9152]

Prof Bhadeshia, which one gives more hardening coherent precipitate or incoherent one? And why?

[@bhadeshia123]

Either can do so, depending on number density, sizes etc. See Reed-Hill, Physical Metallurgy for relevant equations

[@ayay9835]

How coherency reduces coarsening rate ?

[@bhadeshia123]

Lower interfacial energy per unit area

great lecture!!
