“…To select alloy compositions and optimal quenching conditions that provide the best amorphizing ability, one can use an analysis of the temperature and concentration dependences of melt viscosity, undercoolability and features of structure formation during solidification in a wide range of cooling rates. As we have shown earlier [12,14], this approach makes it possible to effectively predict the optimal quenching conditions for obtaining alloys with the highest proportion of the amorphous phase.…”

“…Recently, studies of the influence of such additions on the amorphizing ability and properties of these alloys have been actively conducted [8][9][10][11]. For increase of the GFA of alloys, it is important both to choose the composition of the alloy and to determine the optimal conditions for their production from the liquid phase (quenching temperature, thermal treatment of the melt) [12,13]. To select alloy compositions and optimal quenching conditions that provide the best amorphizing ability, one can use an analysis of the temperature and concentration dependences of melt viscosity, undercoolability and features of structure formation during solidification in a wide range of cooling rates.…”

Atmospheric plasma spraying (APS) technique is employed to prepare Fe-based amorphous coatings on T91 steel substrate under various arc powers of 30 kW, 35 kW and 40kW. The morphology and microstructure of both Fe-based powders and amorphous coatings are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, the wear resistance and high-temperature oxidation resistance of the plasma-sprayed coatings at various arc powers are studied. It is found that with increasing the arc power, the content of the porosity and the amorphous phase in the coatings declines. Specifically, under 30 kW, 35 kW and 40 kW arc power, the porosity of the coatings is 7.96%, 6.13% and 5.75%. Correspondingly, the relative content of amorphous phase from the coatings is measured to be 96.07% (mass fraction), 73.89% and 65.54%. Moreover, under 40 kW arc power, it gives the coating the highest micro-hardness having more compact microstructure and more dispersive α-Fe grains. Besides, the coatings fabricated at high arc power exhibit less wear induced weight loss and less weight gain from high-temperature oxidation comparing with those fabricated at lower arc power.

“…Phase selection pathways in glass-forming metallic liquids are influenced by the development of short-and medium-range order [1][2][3][4][5][6][7][8][9][10], which contribute to local energetics and dynamics. Even in binary glass-forming systems, clear evidence of the influence of ordering in the liquid state has been reported [3][4][5][11][12][13][14][15][16][17].…”

Abstract:The liquid-phase enthalpy of mixing for Al-Tb alloys is measured for 3, 5, 8, 10, and 20 at% Tb at selected temperatures in the range from 1364 to 1439 K. Methods include isothermal solution calorimetry and isoperibolic electromagnetic levitation drop calorimetry. Mixing enthalpy is determined relative to the unmixed pure (Al and Tb) components. The required formation enthalpy for the Al 3 Tb phase is computed from first-principles calculations. Based on our measurements, three different semi-empirical solution models are offered for the excess free energy of the liquid, including regular, subregular, and associate model formulations. These models are also compared with the Miedema model prediction of mixing enthalpy.
