What is Hardness - Definition Material Properties

2021-7-20  In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching. Hardness is probably the most poorly defined material property because it may indicate resistance to scratching, resistance to abrasion, resistance to indentation or even resistance to shaping or localized plastic deformation. Hardness is important from an engineering standpoint

Material Hardness - from Types of Hardness to

2020-6-16  Mohs hardness test uses 10 reference materials of varying hardness as the scale for the test. The softest material used is talc (value=1) and the hardest material is diamond (value=10). Given that the references used for the Mohs scale do not have a graded increase, the Mohs scale lacks accuracy and is only a rough measure of hardness.
