对比了冷轧和冷拔两种不同工艺下,铁铬铝合金丝在表面状态、高温氧化增重率、合金含量的变化、氧化膜及其断口形貌等方面的差异,研究证明,冷轧合金丝比冷拔丝具有较优良的高温抗氧化性能。
The differences of surface morphology, oxidation rate of weight gain, alloy content, oxide film and fracture morphology of Fe-Cr alloy wire under cold-rolling and cold-drawing were compared. The results show that cold-rolling Alloy wire has better high temperature oxidation resistance than cold drawn wire.
