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…
