A Study on the localized corrosion and repassivation kinetics of Fe-20Cr- x Ni ( x = 0–20 wt%) stainless steels via electrochemical analysis

High strength and ductility in partially recrystallized Fe40Mn20Cr20Ni20 high-entropy alloys at cryogenic temperature

“…The yield strength, fracture trength and fracture strain are exhibited in Figure 8B. As can be found in Figure 8A and B, the yield strength of the hot-rolled Fe 40 Mn 20 Cr 20 Ni 20 HEA is 380 Mpa, which is more than double those of Fe-20Cr-10Ni [18] , Fe-20Cr-12Ni [19] , and Fe-16Cr-10Ni steels [20] . Moreover, the elongations are also increased.…”

Growth kinetics and passive behavior of the native oxide film on additively manufactured AlSi10Mg versus the conventional cast alloy

“…Besides having a direct influence on the adhesion, friction, and thermal stability of the material, the native oxide on the surface of numerous metals and alloys represents a natural protective layer against corrosion [1][2][3][4]. Studying the growth kinetics of these oxide films is very important for understanding the mechanisms of stress corrosion cracking (SCC) and corrosion fatigue [5][6][7][8]. A low susceptibility to stress corrosion, and in general, the maintenance of a low corrosion rate, is associated with the possibility of fast reformation of the passivating oxide film on the surface when damage is caused to the material.…”
