The image of hall petch equation is represented below. To calculate hall petch equation, three essential parameters are needed and these parameters are Average Size Diameter (d), Constant (σo) and Constant (ky).
The formula for calculating hall petch equation:
σy = σo + kyd-0.5
Where:
σy = Hall Petch Equation
d = Average Grain Size Diameter
σo, ky = Constants
Given an example;
Find the hall petch equation when the average grain size diamter is 8, the constant is 4 and the constant is 2.
This implies that;
d = Average Grain Size Diameter
σo = Constant = 4
ky = Constant = 2
σy = σo + kyd-0.5
σy = 4 + (2)(8)-0.5
That is, σy = 4 + (2)(0.35)
σy = 4 + (0.707)
σy = 4.707
Therefore, the hall petch equation is 4.707 Pa.
