The Vickers test method involves pressing the indenter into the test material and measuring the diagonal lengths of the indentation left after the load is removed. The basic principle, as with all common measures of hardness, is to observe a material’s ability to resist plastic deformation from a standard source. The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units.

Calculating the hardness of the material is straightforward using the above mentioned formula, and the Vickers hardness is expressed in this form xxxHVyy or xxxHVyy/zz. Where xxx stands for the Vickers hardness number, yy is the load, and zz is if the dwell time is beyond the approved standard of 10 to 15 seconds. For example, the load applied ranges between 1 gf to 120 kgf, which depends on the material being tested. The indenter must contact the specimen at a controlled velocity between 15 and 70 μm/s, not exceeding 0.2 mm/s.

Among all hardness testing methods, the Vickers test is preferred for sintered metal due to its precision and adaptability. This allows for accurate measurement of the matrix hardness while minimizing errors caused by surface porosity. Industrial applications require industrial-strength hydraulic systems—like those built with Danfoss piston pumps. A Vickers hardness tester is the ideal solution for precision hardness measurement of small, thin, or delicate materials.

• In the world of materials science and metallurgy, Vickers Hardness Test is one of the processes used to determine material hardness.

{

• The indentation made by using the indenter must have a properly defined shape to be able to be measured.

• The load is applied for a standard period of about 10 to 15 seconds, and the two diagonals of the indentation created are measured using a microscope.

• The hardness of a material can also be expressed in terms of the load used, for example, HV5 means the hardness calculated for a 5kg load.
• For example, the load applied ranges between 1 gf to 120 kgf, which depends on the material being tested.

• In 1927, Vickers merged with Tyneside based engineering company Armstrong Whitworth to become Vickers-Armstrongs.

Comparison with Other Hardness Tests

The Vickers hardness test is ideal for evaluating very small areas, thin materials, and coatings with high accuracy. With innovations spanning from alternative energy and civil engineering to manufacturing and marine, we’re one of the world’s most trusted industrial hydraulic solution partners. As a worldwide leader, Vickers Hydraulics designs and manufactures a comprehensive line of reliable, high-efficiency hydraulic systems and components. In 1960, the aircraft interests were merged with those of the Bristol, English Electric and Hunting Aircraft to form the British Aircraft Corporation (BAC). This was owned by Vickers, English Electric and Bristol (holding 40%, 40% and 20% respectively). The Supermarine operation was closed in 1963 and the Vickers name for aircraft was dropped in 1965.

The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure. The load is applied for a standard period of about 10 to 15 seconds, and the two diagonals of the indentation created are measured using a microscope. The hardness of a material can also be expressed in terms of the load used, for example, HV5 means the hardness calculated for a 5kg load.

• The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH).
• This indenter is applied onto the surface of the test material with force from a load, which ranges from a few grams to 100 kgf.
