Tribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron
In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16 volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...
متن کاملThe Effect of Flux type and Oxygen Blowing on Simultaneous Removal of Phosphorus and Sulfur from Molten Iron
This research was conducted to study the effect of lime based Flux with the composition of CaO-20%CaF2-8%FeO on simultaneous removal of phosphorus and Sulfur from hot metal. The effects of Na2O and oxygen blowing were also studied. The experiments were performed using an induction furnace and hot metal produced in Isfahan Steel Company in the temperature range 1350-1450 ºC...
متن کاملIron� High Magnetic Field Behavior of Impurities Chromium� In
THE PRESENCE of small amounts of iron in chromium metal results in a lowering of the Neel temperature along with other anomalous diagram[l, changes in the phase r 1 , 2]. Suscepti[I] N eel bility measurements 1 below the temperature show that the iron sites have associated with them localized magnetic moments of about 1·4f.LIJ I· per iron atom and that the iron moments remain paramagnetic do...

متن کاملTHE EFFECT OF CRYOLITE NA3ALF6 AND SODIUM FLUORIDE NAF ON THE CORROSION AND WETTING BY MOLTEN AL-SI ALLOY OF ANDALUSITE BASED REFRACTORIES
In order to improve the corrosion resistance of aluminosilicate refractories by molten aluminum, alkaline fluoride NaF and cryolite Na3AlF6 powders were studied. Both physical and chemical properties are known to influence wetting and corrosion behavior. This paper devoted to determine the influence of alkaline fluoride and cryolite added to andalusite based castable on the reaction with a...
