Abstract

The fracturing of structural steels in Charpy ductile range is investigated. The dependences load versus deflection and time were recorded and the consumption of energy for different fracturing events, as f.i. plastic deflection and crack propagation was assessed. The micromorphology of the crack surface and lips is examined and the succesions of decohesion mechanims is deduced. The aproximate change of fracturing temperature due to adiabatic dissipation of deformation energy as heat is deduced, also.
