The image above represents vicker’s hardness number. To calculate vicker’s hardness number, two essential parameters are needed and these parameters are Load Applied (P) and Diameter of Indenter (d).
The formula for calculating vicker’s hardness number:
HV = 1.854P/d²
Where:
HV = Vicker’s Hardness Number
P = Load Applied
d = Diameter of Indenter
Given an example;
Find the vicker’s hardness number when the load applied is 14 and the diameter of indenter is 2.
This implies that;
P = Load Applied = 14
d = Diameter of Indenter = 2
HV = 1.854P/d²
That is, HV = 1.854(14)/(2)²
HV = (25.95)/(4)
HV = 6.489
Therefore, the vicker’s hardness number is 6.489.
Calculating the Load Applied when the Vicker’s Hardness Number and the Diameter of Indenter are Given
P = HV(d2) / 1.854
Where:
P = Load Applied
HV = Vicker’s Hardness Number
d = Diameter of Indenter
Let’s solve an example;
Given that, the vicker’s hardness number is 6 and the diamter of indenter is 4. Find the load applied?
This implies that;

HV = Vicker’s Hardness Number = 6
d = Diameter of Indenter = 4
P = HV(d2) / 1.854
P = 6(42) / 1.854
So, P = 6(16) / 1.854
P = 96 / 1.854
P = 51.77
Therefore, the load applied is 51.77.

Calculating the Diameter of Indenter when the Vicker’s Hardness Number and the Load Applied are Given
d = √1.854P / HV
Where:
d = Diameter of Indenter
HV = Vicker’s Hardness Number
P = Load Applied
Let’s solve an example;
Find the diameter of indenter when the vicker’s hardness number is 20 and the load applied is 2.
This implies that;
HV = Vicker’s Hardness Number = 20
P = Load Applied = 2
d = √1.854P / HV
d = √1.854(2) / 20
So, d = √3.708 / 20
d = √0.1854
d = 0.430
Therefore, the diameter of indenter is 0.430.
