开发了一种新型的制备氧化物弥散强化(ODS)铁素体钢的方法,用该方法研制的12Cr--ODS钢具有优异的室温和高温拉伸强度、较低的韧脆转化温度、良好的抗蠕变性能和抗辐照肿胀性能.分析了预合金粉末中氧化物(Y2O3)经焙烧热分解、热等静压的界面反应和热变形析出过程和演化行为,并提出选用合理的工艺技术有利于氧化物强化相均匀化.
A new method of preparing ODS ferritic steels was developed. The 12Cr - ODS steels developed by this method have excellent tensile strength at room temperature and high temperature, low ductile brittle transition temperature and good The anti-creep property and the anti-radiation swelling performance of the pre-alloyed powders were analyzed.The interfacial reaction and thermal deformation of the oxide (Y2O3) in the prealloyed powders were analyzed by calcination thermal decomposition, hot isostatic pressing and evolutionary behavior, and the reasonable process Technology is conducive to oxide-enhanced phase homogenization.
