“…The alloy 16-2 has the highest yield stress within the 2% Ta series. This is contradictory to the behaviour of the binary alloys, where the effect of strengthening by entering the DO 3 region is well known [22,23]. The complex variation may be caused by the differing Ta solubility in Fe-Al alloys, where the Ta solubility increases as the Al content increases.…”

“…changes is a function of temperature as well [22,23]. The DO 3 -ordered Fe 3 Al phase has a limited stability over the range of Al contents and it is only stable up to a maximum temperature of about 550 8C.…”

“…As a result, the quenched specimens are expected to be ordered and to possess small APD structures whose presence may contribute significantly to the z, term in (9). A quantitative estimate of this contribution, z~p~, can be obtained by extension of a method first given by Cottrell [38, 411.…”

The compressive deformation behavior of polycrystalline iron-aluminum alloys has been investigated (i) at 298 OK for specimens heat treated in various ways and containing from 22.0 t o 31.7 atyo Al, and (ii) from 77 to 655 OK for well-annealed specimens containing 26.6 atyo 81. Alloys which possess significant DO, type long range order exhibit marked composition and temperature dependent variations in deformation behavior. Specifically, those containing 2 27 atyo A1 exhibit two linear and one parabolic deformation stage at 298 O K . The linear stages are shown to be a result of the production and motion of DO, type superlattice dislocations. The absence of these stages in well-annealed specimens is attributed to the lack of thermal assistance for the DO, superlattice dislocation nucleation process. The flow stress levels which characterize the two linear stage behavior agree with calculations of the stresses required for production of antiphase boundaries. Results obtained from quenched specimens are in agreement with the above conclusions, and the changes induced by quenching are in accord with calculations of the effect of thermal antiphase boundaries upon dislocation motion.
