Categories Related to Hardness Tests
A hardness test is an assessment conducted to measure a material's hardness. This test is critical in industrial applications as it allows for the inference of various mechanical properties from the obtained hardness value.
Characterized by a range of methods and relative simplicity, it is crucial to choose the right test, as definitions and values of hardness can vary significantly depending on the technique used.
Hardness tests are primarily used to estimate mechanical properties such as strength, tensile strength, and wear resistance, based on the hardness value. These tests are advantageous for their speed and simplicity compared to other material tests.
However, for materials with high impurities or complexities, where hardness values alone may be insufficient, additional tests like tensile or impact tests, and metallographic analysis may be necessary.
There are two main principles used in hardness testing:
This method involves pressing objects of various shapes into the specimen and determining hardness from the resulting indentation. It's the most widely used principle for hardness testing.
This method involves striking a sphere against the specimen and determining hardness based on the sphere’s rebound parameters. It’s less accurate than indentation testing but does not damage the specimen.
Several common methods are used in hardness testing:
