How to Calculate and Solve for Avrami Equation | Phase Transformation

Last Updated on December 12, 2022

The image above represents avrami equation.

To compute for avrami equation, three essential parameters are needed and these parameters are Time (t), Time Independent Constant for the Reaction (K) and Time Independent Constant for the Reaction (n).

The formula for calculating avrami equation:

y = 1 – exp(-Ktn)

Where:

y = Avrami Equation
K = Time Independent Constants for the Reaction
n = Time Independent Constants for the Reaction
t = Time

Let’s solve an example;
Find the avrami equation when the time independent constant for the reaction is 18, the time independent constant for the reaction is 10 and the time is 12.

This implies that;

K = Time Independent Constants for the Reaction = 18
n = Time Independent Constants for the Reaction = 10
t = Time = 12

y = 1 – exp(-Ktn)
y = 1 – exp(-(18)(12)10)
y = 1 – exp((-18)(61917364224))
y = 1 – exp(-1114512556032)
y = 1 – 0
y = 1

Therefore, the avrami equation is 1.
