The fracture toughness of a number of cemented carbide alloys have been determined; using a wedge-impact method for precracking. The materials were of WC-Co type with cobalt content ranging from 6 to 25 wt-% and mean carbide grain size between 1.0 and 3.3 pm. Within the investigated composition rang
The variation of fracture toughness with specimen thickness for Comsteel En25 compact tension specimens ranging in thickness from 4 mm to 25 mm and tempered from the asquenched state to 600Β°C is predicted reasonably well using the models proposed by Bluhm Proc. ASTM 61, 1324 (1961) and by Hahn er al
