观察分析了Fe-6.5% Si合金冷轧前后及在不同再结晶退火过程中的组织、织构及有序结构的特点及其演变规律,用以分析织构形成机制及其影响因素.结果表明,间隙溶质原子偏聚于{110}面的概率大于{112}面,明显提高位错在{110}面滑移的临界分切应力;代位溶质原子有可能同步提高{110}和{112}面的临界分切应力,降低这两面的临界分切应力差;因此溶质原子都会导致{112}面更活跃的滑移和更强的{100} <110>冷轧织构.退火过程中{111} <112>取向晶粒易于长入{001}<110>和{112} <110>取向形变晶粒,使{111} <112>再结晶织构增强.冷变形会降低合金的有序化程度;DO3有序化过程的二级相变特点使之在退火加热过程中先于再结晶出现,再结晶之前的回复会促进有序化过程.
