对具有L12有序和A1（fcc）无序结构的正化学计量比Ni 3 Fe合金进行冷轧并在临界有序温度（Tc）以下和以上进行退火，研究有序和无序结构对变形和再结晶过程中织构和显微组织演变的影响。Ni 3Fe合金的冷轧织构基本上显示为铜（纯金属）型，而与冷轧前的有序或无序状态无关。然而，对于初始有序试样的轧制织构，与C {112}和S {123}组分相比，Bs {011}组分增强。在初始有序结构中的轧制织构的强度比在初始无序结构中的弱。此外，立方{001}<$100 <$m织构的强度，这是在再结晶后形成的Tc以上，在最初的有序结构中显着降低。在退火过程中，Ni_3Fe合金在达到Tc后发生轻微硬化，然后迅速软化，无论冷轧前的有序或无序状态。研究还发现，在初始有序结构中的再结晶比在初始无序结构中的再结晶发生得更快且在更低的温度下发生。
Just-stoichiometric Ni3Fe alloy with L12ordered and A1 (fcc) disordered structures were cold rolled and annealed below and above the critical ordering temperature (Tc) to study the effects of ordered and disordered structures on texture and microstructure evolution during deformation and recrystallization. The cold rolling textures of the Ni3Fe alloy basically showed a copper (pure-metal) type irrespective of ordered or disordered state before cold rolling. However, for the rolling texture of the initially ordered specimen, Bs {011}〈211〉 component was enhanced in comparison with C {112}〈111〉 and S {123}〈634〉 components. The intensity of the rolling texture was weaker in the initially ordered structure than in the initially disordered structure. Also, the intensity of a cube {001}〈100〉 texture, which was formed after recrystallization above Tc, was significantly reduced in the initially ordered structure. During annealing, the Ni3Fe alloy slightly hardened up to Tcand then softened rapidly, regardless of ordered or disordered state before cold rolling. It was also found that the recrystallization occurred faster and at lower temperature in the initially ordered structure than in the initially disordered structure.
