摘要(Abstract)：

利用热等静压(Hot isostatic pressing,HIP)和放电等离子烧结(Spark plasma sintering,SPS)工艺制备了氧化物弥散强化(Oxides dispersion strengthened,ODS)钢,采用电子背散射衍射技术、透射电镜和小角度X射线衍射技术等观察了两种工艺制备的ODS钢的微观结构特征,分析了HIP和SPS工艺对ODS钢中析出相种类及分布密度的影响,测试了两种工艺制备的ODS钢在不同温度条件下的拉伸性能。结果表明:HIP工艺制备的ODS钢的晶粒尺寸更加均匀,而SPS工艺制备的ODS钢的晶粒存在明显的双峰分布特征;两种工艺制备的ODS钢中均发现了大量均匀弥散分布的纳米团簇和少量Y_2Ti_2O_7相的存在; HIP和SPS工艺制备的ODS钢中纳米团簇的分布密度分别为1.33×10~(23)个/m~3和4.72×10~(22)个/m~3; HIP制备的ODS钢具有更加优异的拉伸性能。
