“…However, to date, the clear understanding of various factors influencing the occurrence of this event remains elusive as a result of the complexity of their different interactions. Both material-dependent parameters, such as a stacking fault energy of austenite in steels and β phase stability in Ti alloys [2,5], as well as external/loading conditions (temperature, uniaxial tensile, plane strain compression, cyclic loading, high pressure torsion) [2,[4][5][6][7] are examined in this Special Issue.…”
