Vickers was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law George Naylor in 1828. Naylor was a partner in the foundry Naylor & Sanderson and Vickers’ brother William owned a steel rolling operation. Edward’s investments in the railway industry allowed him to gain control of the company, based at Millsands and known as Naylor Vickers and Company. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems. Airflex industrial clutches and brakes are world-renowned for their superior performance, long life and high quality. In 1927, Vickers merged with the Tyneside-based engineering firm Armstrong Whitworth to form Vickers-Armstrongs.

• 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage & Wagon.

In 1929, the acquired railway business was merged with that of Cammell Laird to form Metropolitan Cammell Carriage & Wagon. In 1928, the Aviation Department became Vickers (Aviation) Ltd and soon after acquired Supermarine, which became the “Supermarine Aviation Works (Vickers) Ltd”. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage & Wagon.

Vickers Pumps

Even on the most exacting industrial applications, you’ll find our directional controls keep your maintenance simple and downtime at a minimum. Your choice of pump is backed by Vickers know how, assuring that you get the exact pump needed for the job. In 1919, the British Westinghouse electrical company was taken over as the Metropolitan Vickers Electrical Company; Metrovick.

Is The Indentation Damage Made During Vickers Test A Contributing Factor to Analyzing The Tested Material?

Elevate your systems to new heights with the unmatched power and precision of Vickers hydraulic solutions. The average of the diagonal measurements is taken to get the single value to be used in the Vickers hardness test formula. In the world of materials science and metallurgy, Vickers Hardness Test is one of the processes used to determine material hardness. Hardness testing generally aids engineers in assessing the strength, durability, and wear resistance of a material. Vickers by Danfoss industrial valves give you their best day in, day out, in both stationary and mobile hydraulic applications. Vickers®, one of the most experienced and respected names in hydraulics, became part of Danfoss in 2021.

• 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).

|}{

• 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.

{

• 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.

Load Application

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.

Current status of Vickers

The indentation made by using the indenter must have a properly defined shape to be able to be measured. The indenter is used to apply the load to the test sample for a dwell time Vickers of about 10 to 15 seconds. The Vickers test follows standards such as ASTM E384 or ISO 6507, and can be very useful for comparative studies. In 1921, the Vickers Hardness Test was developed by Robert L. Smith and George E. Sandland at Vickers Ltd. Vickers Hydraulic Valves are available with or without integral relief valve section and are suitable for pressures up to 3000 psi.

The indenter used is diamond-shaped with a square base, and the opposite faces have an angle of 136° between them. 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. A Vickers hardness tester is used to measure the hardness of materials by applying a pyramid-shaped diamond indenter under a controlled force.
