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.
