Dynamic impact behavior and ferrite variation of special stainless steels

Inverse effect of strain rate on mechanical behavior and phase transformation of superaustenitic stainless steel

“…Furthermore, the true stress-strain curves for monophasic superaustenitic 254 SMO steel exhibit a higher true stress at a dynamic strain rate of 5 • 10 3 s À1 than at 8.5 • 10 2 s À1 [3]. The diffuse Lu ¨ders band appears at the surface of soft superaustenitic 254 SMO steel after impact at the higher strain rate of 5 • 10 3 s À1 [3].…”

“…In addition to its remarkable chemical properties, the fatigue properties of low cycle fatigue of superaustenitic 254 SMO steel are superior to those of duplex stainless steels [2]. Furthermore, the true stress-strain curves for monophasic superaustenitic 254 SMO steel exhibit a higher true stress at a dynamic strain rate of 5 • 10 3 s À1 than at 8.5 • 10 2 s À1 [3]. The diffuse Lu ¨ders band appears at the surface of soft superaustenitic 254 SMO steel after impact at the higher strain rate of 5 • 10 3 s À1 [3].…”
