Formula Used in “Vickers Hardness Number Calculator”
The Vickers Hardness Number (VHN) is a crucial metric used to determine the hardness of materials. The formula to calculate the Vickers Hardness Number is defined as:
VHN = frac{1.854 cdot F}{d^2}
Where:
Step-by-Step Breakdown of the Formula
- F: This is the applied force in kilograms-force (kgf) during the hardness test.
- d: This represents the average diagonal length of the indentation made by the diamond indenter, measured in millimeters (mm).
Calculation Process
To compute the Vickers Hardness Number, follow these steps:
- Measure the applied force (F) in kilograms-force (kgf).
- Conduct the indentation test using a diamond indenter and measure the indent’s diagonal length (d) in millimeters (mm).
- Square the diagonal length (d) by multiplying it by itself.
- Calculate the Vickers Hardness Number using the formula provided above.
Example Calculation
To illustrate the use of the Vickers Hardness Number Calculator, consider these sample values:
| Parameter | Value | Unit |
|---|---|---|
| Applied Force (F) | 10 | kgf |
| Diagonal Length (d) | 0.5 | mm |
Now, let’s calculate the Vickers Hardness Number:
- Step 1: Apply the force: F = 10 kgf.
- Step 2: Measure the diagonal length: d = 0.5 mm.
- Step 3: Square the diagonal:
- d² = 0.5 mm × 0.5 mm = 0.25 mm².
- Step 4: Substitute values into the formula:
VHN = frac{1.854 × 10}{0.25} = frac{18.54}{0.25} = 74.16.
Final Result
The calculated Vickers Hardness Number is 74.16 HV.
This simple example illustrates how the Vickers Hardness Number Calculator functions in practice, helping professionals in fields like materials science and engineering make informed decisions. For more information on materials testing and hardness scales, please refer to authoritative sources.

Understanding the Input Fields
Each input field in the Vickers Hardness Number Calculator is crucial for obtaining accurate results.
- Load (kgf or Newton): The force applied during the test. This is important because the greater the load, the greater the indentation depth. For example, a load of 10 kgf is common for testing softer materials.
- Indenter Size: Refers to the dimensions of the diamond pyramid used for indentation. Smaller indenters create less significant indentations, making them suitable for harder materials. For instance, a 100-gram indenter is often used for mild steel.
Examples:
If your test load is 20 kgf and you are using a 100-gram indenter, be sure to enter these values correctly in the respective fields. The accuracy of the VHN depends significantly on these values.
How to Interpret the Results
The output from the Vickers Hardness Number Calculator is a single number, which represents the hardness of the material tested. This number is crucial for material selection, quality control, and research purposes.
- Understanding Output: A higher Vickers Hardness Number indicates a harder material. For example, mild steel may have a VHN ranging from 120 to 150, while hardened steel can exceed 800.
- Common Mistakes: Ensure that the load and indenter size are accurately entered. A common error is confusing units (kgf vs. Newton). Always double-check your input values for the most reliable output.
For further details on Vickers hardness testing methods and standards, you can refer to ASTM E384.
Utilizing the Vickers Hardness Number Calculator effectively will ensure you obtain precise and actionable results, aiding in materials science applications.
