Résumé / Abstract
Transmission electron microscopy in situ straining experiments have been performed on the multiphase alloy Ni-20Al-30Fe (where the composition is in atomic per cent). This alloy consists of the B2 (ordered b.c.c.) phase Ni-30Al-20Fe and the phase Ni-12Al-40Fe which is f.c.c. with fine L1
2 (ordered f.c.c.) particles. Slip in the B2 phase was by the movement of <100> dislocations occurring either on discrete slip planes or in bands and produced loops as debris behind the gliding dislocations. Slip in the f.c.c. L1
2 phase was by the glide of pairs of (a/2)<110> dislocations and occurred on discrete slip planes
