The fraction transformed (fraction of the total amount that could be precipitated were the reaction to go to completion) x as a function of annealing time, t, may be computed directly from the measured values of R(t). x(t)=RS−R(t)/RS−RT. x(t) approximately follows the relation, x(t)=1−exp(−(kt)m), wRead more
The fraction transformed (fraction of the total amount that could be precipitated were the reaction to go to completion) x as a function of annealing time, t, may be computed directly from the measured values of R(t).
See lessx(t)=RS−R(t)/RS−RT.
x(t) approximately follows the relation, x(t)=1−exp(−(kt)m), where κ is the effective rate constant for precipitation and m is the Avrami exponent, which provides information about the precipitation mechanism.
Number of nuclei depends on active sites it generates during the substrate growth.
