The solute drag effect of phosphorus (P) in the single-phase austenite (γ-Fe) region was studied under isothermal annealing conditions at temperatures 1050°C, 1150°C, 1250°C and 1350°C. High-temperature laser scanning confocal microscopy (HT-LSCM) used to observe quantify situ grain growth on surface three different samples containing 0.026 wt.-% P, 0.044 P 0.102 P. dependence arithmetic mean sizes time temperature were modeled mathematically using a simple ordinary differential equation...
The dissolution of amorphous SiO 2 particles in CaO – Al O 3 slags was investigated at 1450°C by high‐temperature confocal scanning laser microscopy ( HT ‐ CSLM ) and thermodynamic/kinetic analyses. used this experimental study had a spherical form so that any rotation the particle did not cause errors determination size during dissolution. Moreover, wide composition range slag could be chosen without forming solid reaction layer which distort evaluation mechanism. evolution diameter...
High temperature confocal scanning laser microscopy (HT‐CSLM) is used to study the dissolution behavior of Al 2 O 3 inclusions in various slag compositions system CaO‐Al ‐SiO ‐MgO. This method enables situ observation at steelmaking temperatures. The change diameter spherical inclusion measured by image analysis pictures obtained from HT‐CSLM. Subsequently, rates and normalized curves are determined, governing mechanism identified use a modified approach diffusion equation introduced...
Hydrogen has received substantial attention because of its diverse application in the energy sector. Steam methane reforming (SMR) dominates current hydrogen production and is least expensive endothermic reaction to produce grey hydrogen. This technology provides advantages low cost high efficiency; however, it emits an enormous amount CO2. Carbon capture storage (CCS) helps reduce these emissions by 47% 53%, producing blue Methane pyrolysis alternative SMR that produces (ideally) CO2-free...
Inclusions chemistry of Mn/Si deoxidized steel was studied through both thermodynamic computation and experimental method. The computational thermodynamics has proved to provide a powerful tool for controlling inclusions precipitates in steel. For steels, important factors determining the liquidus temperature primary phase are MnO/SiO2 ratio Al2O3 content inclusions. Provided that no further interaction with matrix during cooling, having mass% near unity range 10-20 give low temperatures...
Abstract Various aspects of the modeling short-range order in binary and ternary solutions using Bragg – Williams (random mixing), associate, quasichemical models are examined. The compared with respect to their ability predict properties from optimized model parameters presence order. It is shown how introducing through can explain observed flattened shape most miscibility gaps. combination for nearest-neighbor remaining lattice interactions described.
Nozzle clogging during continuous casting of Ti-ULC (Ultra Low C) steel was investigated by inspections plant-used SENs and laboratory scale experiments using a rotating finger method. Various Al/Ti ratios in the different kinds nozzles (with or without CaO) were employed. Clog deposits found used composed complicated oxide (CaO–Al2O3–TiOx-…), Fe drops chunks. Increasing Ti concentration increased amount deposit metallic deposits. In experiments, increasing effective to suppress formation...
