摘要(Abstract)：

对Cr25耐热钢进行1150℃×5 h扩散退火,570℃×5 h去应力退火两种退火工艺处理,并利用X射线(XRD)、扫描电镜(SEM)、能谱分析(EDS)等方法分析合金在1100℃×100 h的氧化增重、氧化膜形貌、相组成及抗氧化机理。结果表明:高温扩散退火后,使原沿晶粒间连续分布的Cr_(23)C_6溶解,提高了铁素体基体的铬含量,并在晶内异位析出,从而使氧化速率由570℃去应力退火时的0.23 mg/(cm~2·h)降至1150℃扩散退火时的0.12 mg/(cm~2·h);同时使氧化膜结构由低温处理时的Cr_2O_3-Fe_2O_3-FeCr_2O_43层结构转变为高温处理时所形成的连续致密Cr_2O_3结构,提高了合金的抗氧化性能。
