Experimental Study of Phase Composition of B-Fe-Mn-V Alloys and Thermodynamic Calculations of Phase Equilibria in the B-Mn-V and B-Fe-Mn-V Systems

Catalytic oxidation of toluene over LaBO3 (B= Fe, Mn and Co) and LaCo0.7B′0.3O3 (B′= Fe and Mn) perovskite-type

In this paper, LaBO3 perovskite type catalyst formulations were prepared by sol-gel auto combustion method using citric acid as the fuel. Activity of catalysts was tested in catalytic oxidation of toluene as a model of volatile organic compounds. LaCoO3 perovskite formulation showed the highest activity among LaBO3 (Fe, Mn and Co) perovskite catalysts. So, LaCoO3 perovskite based catalyst was s...

Magnetic properties of Al, V, Mn, and Ru impurities in Fe–Co alloys

transformation in metastable Fe - Mn alloys

Metastable Fe-Mn alloys exhibit a non-thermoelastic martensitic transformation which is accompanied by a significant thermal effect (ca. 20 J/g). Among Fe-Mn alloys, the highest value of latent heat was registered in alloys with 17-18 wt. % Mn. In this work we investigate effects of carbon (up to 0.4 wt. %) and cold rolling (5-25% of thickness reduction) on the latent heat and the temperature h...
