Abstract Scope |
Hardness is commonly applied to define material’s ability to resist deformation, indentation, and scratches. For tribology related engineering, hardness is an important indicator utilized to analyze materials wear behavior. Various hardness test methods are available commonly defined by scale of hardness measurements, such as bulk, micro, and nano. Among them, microhardness test method (HV10) has been used for testing up to 700°C. However, repeatability of the hot hardness test with diamond indenter cannot meet demand of high temperature materials' application.
Development of a hot hardness measurement method HBJ, was initiated a decade ago at L.E. Jones Company. A significant HBJ database for many high temperature materials has been generated with testing temperature from ambient to 900°C that has confirmed its effective applicability for high temperature materials applications. This presentation provides the basic information useful for engineers and researchers who need materials hot hardness property for product design and application. |
