Light non-magnetic steels based on Fe – 25 Mn – 5 Ni – Al – C system

X-ray diffraction peak profile analysis of maraged Fe-Ni-Mn steels

X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...

Microstructure and Magnetic Behavior Studies of Processing-controlled and Composition-modified Fe-Ni and Mn-Al Alloys

CALCULATION OF THERMODYNAMIC PROPERTIES OF Al-Fe, Al-Ni AND Ni-Fe ALLOYS USING FACTSAGE

Thermodynamic predicting analysis of three binary systems Al-Fe, Al-Ni and Ni-Fe are shown in this paper. Thermodynamic analysis involved calculation of activities, coefficient of activities, partial and integral values for enthalpies and Gibbs energies of mixing and excess energies at three different temperatures: 1873K, 1900K and 1973K, as well as calculated phase diagrams, for the investigat...

Hard magnetic properties of melt-spun Mn-Al-C alloys

Structural and magnetic characterization of Mnx−yAl100−x−yC2y (x = {50, 55}; y = {0, 1}) melt-spun ribbons is reported. To obtain the metastable ferromagnetic τ-phase, rapidly solidified alloys were annealed either in a vacuum furnace at 823 K or directly in the vibrating sample magnetometer under applied magnetic field. Optimal magnetic properties were demonstrated by Mn54Al44C2 samples proved...
