The Vickers hardness test is the most versatile of all the available procedures.Hardness test: The hardness test is a type of mechanical test used to check the material properties. It helps to eliminate the chances of failure of a specimen before its use. A hardness test can be categorized as a micro and macro hardness test. The types of macro hardness tests are the Rockwell hardness test, the Brinell hardness test, and .
Vickers hardness testing to ASTM E92 is a hardness test method with optical evaluation in which the size of the indentation left on the surface of the test material by a pyramid-shaped diamond indenter (square base and interfacial angle of α = 136°) is measured. The test load is applied precisely and the diagonals of the indentations are used to calculate the Vickers .The Rockwell method is a static hardness testing method, which can be further characterised as follows: It is one of the standardised procedures (ISO 6508, ASTM E18). The process is used to test hardness in the macro range (test force >= 49.03 N), more precisely with a test force of 29.42 to 1471 N. It is a differential-depth method.The hardness of metals can be tested by 12 different hardness tests and the Brinell Hardness test is the oldest technique to measure the hardness of metals but is widely used. In this blog, we will discuss only Brinell Hardness test methods, including principle and theory, applications, advantages and disadvantages. ASTM E384: This standard is for hardness testing on a micro-scale, and therefore includes the Vickers and Knoop hardness tests. ISO 6506: This standard mirrors ASTM E10, as it contains the standard method for measuring the Brinell hardness of metals. ISO 6507: This standard contains the details for the Vickers hardness test in metallic materials.
The Rockwell, Brinell, and Vickers hardness testing methods are generally used for different scenarios and situations. However, hardness testing professionals have sometimes found it hard to agree on the most suitable method based on their differences. . Related Article: What are the Advantages and Disadvantages of the Vickers Method? .
The Leeb method is a quick and portable hardness test method, which is determined by the ratio of rebound velocity to the impact velocity of a moving impact body. It is best applied to solid parts of the object for example casting and forgings. In the article, we include the advantages and disadvantages of Leeb method in details.
In certain cases, Rockwell offers compelling advantages. Fast, rough, affordable, and less surface treatment represent some of the key descriptors of this testing method.

Hardness testing within the realm of materials testing. Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find .Due to this shallow indentation depth, the Knoop method is particularly suitable for testing very thin layers (e.g. aluminium foil). Due the long and narrow (elongated) test indent, the Knoop method is best suited for use with small, .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. .
Leeb Hardness Test. Leeb hardness testing is a dynamic test, it uses a impact device to generate a force on the material. A sensor on the material measures the rebound velocity and the hardness value is calculated based on the velocity and the impact device properties. The advantage of Leeb testing is that it can be used to test hard materials .Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting.The advantages and disadvantages of the two test meth-ods come principally from the differently shaped indenters. Vickers testing uses a pyramidal diamond (Fig.1) resulting in . and the average of those two values is used in the calculation of hardness. Knoop testing uses an elongated pyramidal indenter (Fig.2), producing a rhombus-shaped . Therefore, hardness values can only be compared if they have been obtained by identical test procedures. The most important procedures and their advantages and disadvantages are explained in more detail below: Brinell hardness test (explained in this article) Vickers hardness test; Rockwell hardness test
Advantages and disadvantages. The advantage of Rockwell hardness testing is the relatively short testing time and good automation capability, as the measured values are determined directly from the indentation depth without optical measurement under a microscope. This process is therefore particularly suitable for automated production.Vickers hardness testing has been widely used as one of the basic and reliable material test methods. Furthermore, triangular pyramidal indentation technique (the nanoindentation method) is also used to analyze the mechanical characterization of extremely thin films.

Advantages of Vickers Hardness Testing. Versatility: The Vickers test can be applied to a wide range of materials, from very soft to extremely hard, without altering . The Vickers hardness test is based on the principle of indentation hardness, where a diamond indenter with a square-based pyramid shape is pressed into the surface of the material under a specified load. The diagonals of the resulting indentation are measured using a microscope, and the Vickers hardness value is calculated using a formula that .The Brinell hardness HBW results from the quotient of the applied test force F (in newtons N) and the surface area of the residual indentation on the specimen (the projection of the indentation) after removal of the test force (see Brinell formula).To calculate the surface area of the residual ball indentation, the arithmetic mean d of the two perpendicular diagonals d1 and d2 (in mm) is .
