Alterations in Fracture Behaviour of the Cr-V Ledeburitic Steel Vanadis 6 Caused by Plasma Nitriding
Original language description
The three point test specimens made from the VANADIS 6 ledeburitic steel were heat treated using two basic regimes, bringing a different hardness. The cross section of the specimens ranged between 10x10 mm and 1x10 mm. Plasma nitriding was carried out atvarious combinations of the temperature and dwell time. The testing of fracture toughness established the dominant role of the presence of nitrided layer on both the bending strength and the fracture mechanism. Only if the material was not plasma nitrided, the role of the austenitizing temperature became clearly shown ? the higher temperature was the three point bending strength was worse. The character of the initiation and propagation of the fracture was low ? energetic ductile when the material washardened and tempered. The presence of the plasma nitrided region on the surface changes the initiation as well as the propagation mechanism to that of cleavage. The thickness of the cleavage region raises as the nitrided region becomes t
