To avoid slag sticking onto the ladle snorkel during the process of ladle alloying treatment station (LATS), the variation of the ladle slag viscosity before and after LATS refining process was studied. The additives including CaO+CaF2, CaO+B2O3 and Li2O were employed to decrease the viscosity of ladle slag.
The changes of microstructure, phase constituent and microhardness of the Cr Al mixed powders during mechanical alloying treatment have been investigated using X ray diffraction analysis, SEM examination and microhardness testing.
The changes of the powder morphology and microstructure of the mixed powders during mechanical alloying treatment have been studied. It is clear to observe the coalescence and fracture of the powder particles and the formation of multiparticles by SEM.
The structure of the catalyst was modified, and there was an increase in the conversion of ruthenium into the alloyed state and an increase in particle size with the ascension of heat treatment temperature.
Peculiarities of the Transition to an Equilibrium State of Mechanically Alloyed Fe/Amorphous Phase Fe-B/B Nanocomposite with Com
The observed differences are explained by a high thermal stability of the nanostructure in the mechanically alloyed Fe-B system due to the presence of boron atoms Bs segregated at the intergrain boundaries.
Ion-alloyed titanium surface layers that contain finely dispersed discrete intermetallic phases TiAl and Ti3Al, as well as a solid solution of aluminum in titanium, are produced.
The inference is made that the structure and phase composition of the ion-alloyed titanium layers affect their mechanical and tribological properties.
