# How to Calculate and Solve for Vicker’s Hardness Number | Mechanical Properties

Last Updated on January 10, 2023

The image above represents vicker’s hardness number.

To compute for 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/

Where:

HV = Vicker’s Hardness Number
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/
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 is Given.

P = HV(d2) / 1.854

Where:

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
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 is Given.

d = √1.854P / HV

Where:

d = Diameter of Indenter
HV = Vicker’s Hardness Number

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
d = √3.708 / 20
d = √0.1854
d = 0.430

Therefore, the diameter of indenter is 0.430.
