The image above represents initial grain diameter. To calculate initial grain diameter, four essential parameters are needed and these parameters are Average Grain Size Diameter (d), Time (t), Time Independent Constant (k) and Time Independent Constant (n).
The formula for calculating initial grain diameter:
do = (dn – kt)(1/n)
Where:
d = Average Grain Size Diameter
k, n = Time Independent Constants
t = Time
Given an example;
Find the initial grain diameter when the average grain size diameter is 2, the time is 3, the time independent constant is 6 and the time independent constant is 9.
This implies that;
d = Average Grain Size Diameter = 2
k = Time Independent Constant = 6
n = Time Independent Constant = 9
t = Time = 3
do = (dn – kt)(1/n)
do = (29 – (6)(3))(1/9)
That is, do = (512 – (18))(1.992)
do = (494)(1.992)
do = 1.99
Therefore, the initial grain diameter is 1.99 mm.
