In some applications, deep desulfurization and deoxidation of steels without the use aluminum are required, using Si as a deoxidant instead, with double-saturated slags in CaO-SiO2-CaF2-MgO system. This work studied nonmetallic inclusion evolution for system an induction furnace compared results FactSage kinetic simulations. Steel samples were taken from steel melt analyzed ICP-MS combustion an...

The aim of this paper is to evaluate the influence small variations in chemical composition on corrosion resistance and mechanical properties low-manganese medium manganese high strength steels. Six different steels with content varying from 1.5 4.0 wt.% aluminium 0.008 6.5 were subjected analysis. other subjects for evaluation included effect as a replacement silicon, niobium microalloying hea...

Rolling contact fatigue failure is one of the main damages in railway wheels caused by cyclic rolling with rails. This internal defects such as nonmetallic inclusions or voids and may occur heavy haul freight car wheels. The subsurface crack propagation behaviors are evaluated twin-disc-type tests using test specimens artificial defects. Finite element analyses involving simulated also conducte...
