TL;DR: There remains growing interest in magnesium (Mg) and its alloys, as they are the lightest structural metallic materials Mg alloys have the potential to enable design of lighter engineered systems, including positive implications for reduced energy consumption as mentioned in this paper.
Journal ArticleDOI
Influence of Water Vapor and Flow Rate on the High-Temperature Oxidation of 304L; Effect of Chromium Oxide Hydroxide Evaporation
TL;DR: In this article, the effect of Roman PH2O and flow rate on the oxidation of 304 Lat 873 K in oxygen was reported, where high concentrations of water vapor and high flow rate result in breakaway corrosion.
Journal ArticleDOI
Indication of Chromium Oxide Hydroxide Evaporation During Oxidation of 304L at 873 K in the Presence of 10% Water Vapor
TL;DR: In this paper, the oxidation of 304L stainless steel was investigated at 873 K in the presence of O2and O2 + 10% H2O. The oxide layer contained mainly chromium, with smaller amounts of Fe and Mn.
Journal ArticleDOI
Evidence for Chromium Evaporation Influencing the Oxidation of 304L: The Effect of Temperature and Flow Rate
TL;DR: In this paper, the influence of temperature and flow rate on the oxidation of 304L steel in O2/H2O mixtures was investigated, and the results showed that chromium evaporation is a key process affecting the oxidation resistance of chromia formers and marginal chromia-rich oxide.
Journal ArticleDOI
KCl induced corrosion of a 304-type austenitic stainless steel at 600°C; The role of potassium
TL;DR: In this article, the influence of KCl on the oxidation of 304-type (Fe18Cr10Ni) austenitic stainless steel at 600 degrees C in 5% O 2 + 40% H 2 O is investigated in the laboratory.
