Abstract

ISO 28079:2009 specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. ISO 28079:2009 applies to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and carbonitrides (normally called hardmetals, cermets or cemented carbides). The test procedures proposed in ISO 28079:2009 are intended for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures proposed in ISO 28079:2009 are also intended for use in a normal laboratory-air environment. They are not intended for use in corrosive environments, such as strong acids or seawater.
