Özet:

 

The interactions between distinctive alloying elements   have been scrutinized through atomistic investigation for essential material   selection. The tight-binding model was applied to compute the thermodynamic   properties of V, Cr, Mo, and Fe metals and their binary alloys. The   calculated results agree with the accessible experiment in some cases, while   some are closer in agreement with the experiment. The minimum formation   enthalpies observed are -17.80, -15.20, -13.10, -11.50, and -0.90 eV   for Cr-Mo, Cr-V, Fe-V, V-Fe, and Mo-Cr, respectively. The Cr-Mo alloy   is the most stable of all the selected alloys with the least formation   enthalpy. For the alloy structure, bcc phases were observed for   V0.50Cr0.50,V0.01Mo0.99V0.50Cr0.50,V0.01Mo0.99V_{0.50}{Cr}_{0.50}{,\, \, V}_{0.01}{Mo}_{0.99}, V0.50Fe0.50,V0.50Fe0.50,V_{0.50}{Fe}_{0.50},\,   \, and Cr0.01Mo0.99Cr0.01Mo0.99{Cr}_{0.01}{Mo}_{0.99} alloys with values of VEC of \textless   6.87. Furthermore, fcc and bcc coexist for Cr0.50Fe0.50Cr0.50Fe0.50{Cr}_{0.50}{Fe}_{0.50} and   Mo0.50Fe0.50Mo0.50Fe0.50{Mo}_{0.50}{Fe}_{0.50} alloys, which have VEC values between 6.87 and 8.
