The lattice parameter of the metal is approximately Configurational entropy due to ideal mixing in a binary A - B system is expressed as: ΔS mix = - R(X A In X A + X B In X B ), where X A and X B are mole fractions of A and B respectively. ΔS mix is maximum at X A = . . . . . . . . Mould coating material which helps in grain refinement of metal casting is Disintegration rate of a radioactive element
