Abstract: Phase equilibria in Fe-Mn-S and Fe-Cr-S ternary systems at 1 843 K were investigated experimentally, respectively. The main characteristic of these two systems at 1 843 K was confirmed to be a wide miscibility gap between two liquid phases: molten metal alloy phase and molten sulfide phase. Through metal/ sulfide equilibrium method, activity of constituents in sulfide phase were determined in Fe-Mn-S and Fe-Cr-S systems separately. The activity curves of constituents in sulfide phase were estimated by utilizin… Show more

Investigating molybdenum’s sulphur scavenging ability for MoS2 formation in preventing pitting corrosion of stainless steels

The addition of Mo enhances pitting corrosion resistance in 304L stainless steel. However, there is no consensus on the underlying mechanism. One possible explanation is that molybdenum converts sulfide to stable MoS2. This study investigates the effect of MoS2 inclusion on the corrosion of 304L stainless steel by introducing both MnS and MoS2 using spark plasma sintering. The reduction of MoS2 to Mo is observed during the sintering process, contradicting the assumption that the sulfide inclusions can be stabilised by forming MoS2. Therefore, MoS2 formation cannot explain the improved corrosion resistance of 304L stainless steel with the addition of Mo.

Stainless steel is a special category of steel and contains high chromium and nickel.With particular attention to chromium and nickel, the solvent metal phase of recycling of end-of-life (EoL) ferritic and austenitic stainless steels by remelting is considered Fe-Cr alloy and Fe-Cr-Ni alloy instead of pure iron, respectively. Understanding the element elimination behavior from the solvent metal phase during the remelting process is important for the improvement of the resource efficiency of the stainless steel recycling. The elimination behavior of 23 alloying elements from Fe-Cr alloy and 22 alloying elements from Fe-Cr-Ni alloy were quantitatively evaluated by the thermodynamic method. The conventional metallurgical process, including slagging (oxidation) and evaporation, can efficiently eliminate lots of alloying elements but has its limitation for the elimination of some alloying elements such as copper, antimony, and tin. Moreover, improvement of the elimination is hard to expect with optimizing remelting conditions. Developing novel metallurgical refining processes, such as chlorination and sulfurization, is efficient for eliminating specific alloying elements. However, besides the effort from metallurgical technologies, developing advanced physical separation technologies of collected EoL products in the short term and optimizing the alloy/products design principle in the long term are much more important for improving the resource efficiency of recycling of EoL stainless steel products. Feedback of the alloying elements' elimination behavior during the remelting process to the upstream of the stainless steel cycle is critical.

Phase equilibria in Fe-Cr-Mn-S quaternary system at 1 843 K were investigated experimentally. Two liquid phases: molten metal alloy phase and molten sulfide phase were in equilibrium in this system at 1 843 K. The equilibrium relations between molten metal alloy and sulfide phases were experimentally measured. By using metal/sulfide equilibrium method, activity of constituents in molten MnS-CrS-FeS sulfide phase were determined. By utilizing regular solution model, activity curves of constituents in sulfide phase were estimated.
