"Acicular ferrite (AF) microstructure presents an excellent contribution to mechanical properties, toughness and hydrogen embrittlement resistance. Majority of the AF plates (laths) have the mutual high-angle disorientation in contradistinction to the bainite having only the high-angle interfaces between the packets consisting of low-angle plates (laths). The cleavage unit crack path (UCP) has been found to be a distance between two grains of high-angle ferrite regions. In the AF the UCP value is defined as a distance between two neighbouring highly misorientated plates. It shows the UCP values are shorter what results in higher frequency of deviations and consequently in limited (retarded) cleavage crack propagation. In paper optimized thermomechanically controlled process (TMCP) leading to the AF formation is presented." . "Mazanec, Karel" . . . . "Ruck\u00E1, Zde\u0148ka" .
