Large non-metallic inclusions affect the mechanical properties and service life of nickel-based superalloys. This study investigates effects magnesium elements on in K4169 superalloys, exploring formation mechanisms aggregation relationships inclusions. Four gradients content were used to simulate erosion MgO refractories vacuum induction melting The observed mainly comprised MgO, TiN, MgAl2O4, MgAl2O4-TiN composites. To mechanism Ni-based alloys with different Mg contents, predominance...

Steel slag reaction experiments were conducted, and FactSage macro editing was applied to study the kinetics of medium- high-basicity refining with SWRS82B steel. Changes in composition molten steel inclusions observed simulated. The experimental results indicated that oxygen sulfur contents decreased rapidly during first 5 min process, then changed slightly. variation law calculated based on consistent results. number from 27 pcs/mm 2 18–19 their average size reduced 3.51 Î m 2.59–2.49...
In this work, Ti–3Si-1.5Fe–1Mo titanium alloy reinforced with in-situ synthesized Ti 5 Si 3 was prepared, and ultrahigh hardness (55.6 HRC) achieved by solution aging treatment. The effects of on the friction wear behavior were investigated. Results show that rate after hot treatment increases from 3.51 × 10 −4 mm N −1 m to 3.93 , yet exhibits poor resistance. A series tracks characterizations thermodynamical calculations performed elucidate its mechanism: during reciprocating sliding,...
The large primary carbides in H13 steel significantly affect its service life. In this study, pre-dispersion technology is used to disperse CeO2 nanoparticles, which are then introduced into steel. effects of nanoparticles on the inclusions, carbides, microstructures, and properties investigated. Ce-containing inclusions with size 0.5–2 μm generated distributed uniformly owing reduction by Al C. Both dendrite structure refined nanoparticles. secondary arm spacing decreases from 13.51 ± 2.34...
When low-grade high-silica bauxite undergoes desilication by alkaline leaching, a large amount of alkali-silicate solution will be produced. To realize its recycling, the needs to desiliconized. In this study, effectiveness red mud and mixture CaO as reagents are compared mechanisms were analyzed. Results show that when adding 30–50 g/L mud, rate is only 36–38% while 30 with calcium-silicon ratio 1 reaches ∼89%. Analyses SEM-EDS other mean mainly due growth sodalite seed crystals in...
The aluminum oxide inclusions in SWRS82B steel seriously affect the drawing performance of strand. In this study, influence different additions cerium (within range 0–0.034%) on composition, morphology, size, number, and distribution alumina was studied by scanning electron microscope energy spectrum analyzer. evolution composition with calculated based classical thermodynamics Factsage software calculation. thermodynamic results were consistent experimental results. It indicates that...
