If we consider a β precipitate of an almost pure metal B with Interface mobility given as M, Molar volume V of the β phase, and the driving force is given as Δμ. Calculate the flux across the interface?
If we consider a β precipitate of an almost pure metal B with Interface mobility given as M, Molar volume V of the β phase, and the driving force is given as Δμ. Calculate the flux across the interface? Correct Answer J = -MΔμ/V²
Actually, the interface velocity per molar volume is the flux across the surface. The interface energy is given as the product of the interface mobility and the driving force per unit molar volume hence the flux is given as J = -MΔμ/V², here the negative sign indicates that flux is in the negative direction along the oriented axis.
