title = "The fracture toughness of cold work tool steels",
abstract = "The influence of the composition and the microstructure on the plane strain fracture toughness of five cold work tool steels all processed via the powder metallurgical route is investigated using 3-point bending specimens. The steels differ in composition and therefore possess different volume fractions of carbides. The amount, size and distribution of the carbides in the matrix are estimated by quantitative image analysis on a plane parallel to the fracture surface without discrimination of the carbide type, since the carbides are always much harder [1,2] than the matrix, irrespective of their composition. Due to the production of the steels via the powder metallurgical route almost all carbides are spherical in shape. The mechanical in-situ properties of the matrix are characterized by indentation tests performed with an {"}Ultra-Micro{"}-indenter in a scanning electron microscope.",
