Ferritic layer formation occurs after oxidation in Mn-rich austenitic alloys. It has significant effects on high-temperature oxidation resistance, but a better understanding of its formation is needed to control these effects. Thus, two FeMnSiCrNi al

Shape-memory Mn-rich austenitic stainless steels have a low high-temperature oxidation resistance because Mn tends to inhibit the formation of protective oxides. Mn depletion from oxidation also creates a ferritic Mn-depleted layer. A Mn-depleted lay

Conventional stainless steels are used in cyclic oxidation, but the high amount of Cr and mainly Ni increase the price of these alloys. The objective of the present study was to assess the cyclic oxidation resistance of FeSiCrNi and FeMnSiCrNiCe allo

Iron aluminides based on Fe3Al intermetallic structure are known by their good corrosion and oxidation resistance. However, the hydrogen embrittlement is an issue generated by passive Al2O3 formation due to Al reaction with atmospheric water vapor. T

Applications at elevated temperature require alloys that can form a protective oxide layer, and Cr and Si are known to form these layers, allowing FeCrSi alloys to be oxidation resistant. However, few studies have considered Si content higher than 2

The oxidation resistance of an FeMnSiCrNi alloy was recently improved by vacuum heat treatment. However, a detailed characterization was still necessary to understand the effects of the treatment on the material structure and on the oxide evolution.
