Ordering phase relationships in ternary iron aluminides

Coarsening process and precipitation hardening in Fe 2 AlV-strengthened ferritic Fe 76 Al 12 V 12 alloy

“…9. The fitting value of γ APB is stable and in excellent agreement with the values obtained by first principles calculations of a A P B ( /2) 111 (011) in Fe 2 AlTi and Fe 2 AlNb intermetallic at 227 ºC [63]. An average elastic repulsion between the strongly paired dislocations, w = 3.42 ± 0.16, was estimated from the junction of both curves given by Eqs.…”

Characterization of microstructures and age hardening of Fe1−2xAlxVx alloys

“…Note that g APB is experimentally unknown for Fe 2 AlV but we have access to theoretical values for Fe 2 AlNb and Fe 2 AlTi recently obtained by first principles calculation [60]. These values are 0.64 J/ m 2 and 0.57 J/m 2 respectively.…”

Influence of the Cooling Rate on Austenite Ordering and Martensite Transformation in a Non-Stoichiometric Alloy Based on Ni-Mn-In

“…Therefore, the structural order of the austenitic phases depends on the conditions and cooling rate. The papers [6,7] describe methods for the formation of APB in Heusler alloys. In the case of a quenched sample, APBs are formed as a result of a thermally induced order-disorder transition [7].…”

“…In the case of a quenched sample, APBs are formed as a result of a thermally induced order-disorder transition [7]. Or, in the case of slow cooling with a furnace, APBs mainly develop due to the merging of two neighboring L2 1 ordered regions [6].…”
