摘要: Abstract The room-temperature deformation behaviour of a slowly cooled Fe-35·5 at.% Al alloy has been studied in some detail, particularly using transmission electron microscopy. high degree B2 long-range order and DO3 short-range order. A three-stage work-hardening curve is obtained, though the observed stage III thought to be due more compression testing than inherent properties material. Stage I, with its serrated flow, appears yielding phenomenon associated formation very coarse slip bands. It probably related destruction ends when these bands cover specimen. II characterized by linear rate (θII/G∼(1/50)) coupled comparatively low increase primary dislocation density increasing stress secondary (pf/pp-∼(1/100)). Present theories ordered alloys appear unable explain f...
