The Rockwell test is a quick and direct process, while the Vickers hardness test is a slow process and requires other optical devices such as a microscope to measure the hardness of the object.The Vickers hardness test is often regarded as easier to use than other hardness tests: The process can be performed on a universal or micro hardness tester; the required calculations are independent of the size of the indenter; and the same indenter (a pyramidal diamond) can be used for all materials, irrespective of hardness. .
The hardness of steel depends on several factors, such as its composition, manufacturing, and heat-treating processes.The different hardness scales use different loads, different indentor shapes, and different measurements to obtain the hardness number. There are no straightforward formulae to establish relationships between the different scales, making .A Vickers hardness tester. The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter .
