To carry out a hardness test, a constant force must be applied to the material, using a rounded or pointed indenter to form an indentation on the surface of the material. The type of indenter used depends on the type of hardness test being performed. The indentation created on the surface is then measured to determine the material’s hardness.

One of the key advantages of the Vickers Hardness test is its versatility, as it can be applied to a wide range of materials and properties.

Hardness testing is used to optimise heat treatment processes. It helps determine the effectiveness of heat treatments in achieving the desired hardness levels, leading to improved material performance.

Knoop hardness testing is a microhardness testing method used to measure the hardness of materials at a microscopic scale, making it particularly advantageous for testing thin coatings, brittle materials, and materials with a fine microstructure. Hardness is calculated based on the indentation size and is often denoted as HK.

Brinell hardness testing is a method used to determine the hardness of a material, measuring its resistance to deformation when a known force is applied. This test is particularly suited for materials with coarse or granular structures.

Hardness testing is used to optimise heat treatment processes. It helps determine the effectiveness of heat treatments in achieving the desired hardness levels, leading to improved material performance.

Understanding the hardness of a metal or material is crucial to production, as it provides information about how strong the material is, how it will cope in certain environments, and overall mechanical performance.

Hardness testing on metals is used to evaluate the resistance of a metal to deformation or permanent damage, specifically in terms of indentations or scratching. It involves applying a consistent force using a rounded or pointed object under controlled conditions to create a small dent on the surface of a metal. The size of the dent is then measured to determine the hardness of the material.

Our NDT testing team is equipped with various types of portable hardness testing machines, ensuring flexibility and accuracy in different scenarios.

Hardness testing is often used in combination with tensile testing, as both tests can give a thorough overview of a material’s mechanical properties. By evaluating the material’s resistance to indentation, we can gain valuable insight into its strength, durability, wear resistance, and toughness.

Material hardnesspdf

Using a pyramid-shaped diamond indenter to carry out the hardness measurement to lighter loads, Vickers macro and microhardness tests are suitable for softer materials. The specific size, shape, and location requirements of the hardness test determine the use of the Vickers method.

Hardness testing provides valuable information of a material's resistance to deformation, a gives and insight into its strength and durability. This is crucial for ensuring that materials meet the required mechanical properties for specific applications.

To ensure efficient tracking, each sample is given a unique barcode to book all your samples into our laboratory. This allows us to monitor each sample from the moment it arrives, throughout the testing process, until its completion.

Hardness testing is commonly used in quality control, material selection, and research and development to assess the mechanical properties of metals and select the most appropriate material for a specific application.
