(a) tensile and compressive engineering stress-strain curves of TiZr-MG and CM400 UHSS
(b, c) stress-life (S-N) fatigue data for the notched MG and UHSS (Data are presented in terms of the reversal cycles to failure (2Nf), as a function of the applied stress amplitude (σa = (σmax - σmin) / 2) and the applied stress amplitude normalized by the ultimate tensile strength (σa / σUTS), respectively. σmax—the maximum cyclic stress, σmin—the minimum cyclic stress, b—the fatigue exponent, σf'—the fatigue coefficient)
(d, e) surface damage features near the fatigue crack in the notched UHSS and MG
