Publikováno v: Procedia Materials Science. 8:994-1003

Iron rich Fe-Al-V alloys have a considerable potential as structural materials at high temperatures. In previous works we have studied the phase equilibria in the bcc system Fe-Al-V, from computational thermodynamics calculations. There, the vertical

Stability of the C14 Laves phase (Fe,Si)2Mo from ab initio calculations

Autor: Gerardo Hector Rubiolo, Pablo Hugo Gargano, P.R. Alonso

Publikováno v: Calphad. 35:492-498

The C14 Laves compound Fe2Mo has an outstanding influence in thermodynamic and mechanical properties of steels. Silicon has to be taken into account as it stabilizes the Laves phase to a great extent. Since experimental data are difficult to achieve
