What is the Vickers Hardness Test?

The Vickers hardness test is a highly precise method used to measure the hardness of materials across a broad range, from soft metals to ceramics and composite materials. Developed in 1921 by Smith and Sandland at Vickers Ltd., the test employs a diamond-shaped indenter and is suitable for both microhardness (low loads, thin materials, small features) and macrohardness (higher loads, thicker samples) applications.

The resulting hardness value, expressed as Vickers Hardness (HV), is calculated by dividing the applied test load by the surface area of the indentation made by the diamond.

Why Use the Vickers Hardness Test?

The Vickers hardness test offers a unique combination of accuracy, flexibility, and applicability, making it a popular choice in materials science, quality control, and product development:

  • Extremely Precise Measurements: Ideal for small samples, coatings, or fine microstructures where accuracy is paramount.

  • Versatile Testing: Suitable for almost all materials, metals, ceramics, polymers, and composites, regardless of hardness.
  • Consistent Geometry: The symmetrical diamond indenter provides a geometrically consistent indentation, eliminating the need for scale changes across different materials.
  • Wide Load Range: Applicable from as low as 10g (microhardness) to up to 100kg (macrohardness).

  • Minimal Sample Damage: Particularly valuable for delicate or valuable specimens.

  • International Standardisation: Fully compliant with ASTM E384, ASTM E92, ISO 6507, and other global testing standards.

How the Vickers Hardness Test Works

The Vickers hardness test involves a controlled, step-by-step process:

  1. Indenter Application: A four-sided diamond pyramid indenter is pressed into the sample surface using a defined force (load), held for a set dwell time.

  2. Indentation Creation: The diamond creates a square-shaped impression on the material’s surface.

  3. Measurement: The diagonals of the square indentation are precisely measured using an optical microscope or a digital camera system.

  4. Calculation: The Vickers hardness number (HV) is calculated using a standardised formula based on the applied force and the average length of the diagonals.

This method provides a high degree of accuracy and resolution, particularly valuable for testing very small areas or thin sections.

Vickers Hardness Test FAQs

 

Both are microhardness tests, but Vickers uses a square-based pyramid indenter, while Knoop uses an elongated diamond. Vickers is more widely applicable for both macro and micro testing.

Yes, particularly in microhardness mode with lower loads, making it ideal for plated surfaces, PVD coatings, and thin films.

We recommend calibration at least annually, or more frequently in high-use or regulated environments. Indentec offers full calibration and certification services.
