采用溶胶-凝胶法结合氢还原法制备了名义成分为Fe-14 Cr-3 W-0.2Ti-0.3Y的纳米晶氧化物弥散强化（ODS）铁素体钢粉末。X射线衍射分析表明，在1200°C还原3 h后，得到了纯的Fe-14 Cr-3 W-0.2Ti-0.3Y体心立方相。采用放电等离子烧结（SPS）技术制备了ODS钢。能谱分析和透射电镜分析结果表明，Y2 Ti 2 O 7氧化物颗粒均匀分散在钢基体中，平均粒径为55 nm，颗粒数密度为3.2× 1019 m − 3。经SPS烧结和1100°C单向压力机械热处理后的钢的抗拉强度和均匀延伸率分别达到1070 MPa和15%。
Nanocrystalline oxide dispersion strengthened (ODS) ferritic steel powders with nominal composition of Fe–14Cr–3W–0.2Ti–0.3Y was synthesized using a sol–gel method combining with hydrogen reduction. X-ray diffraction patterns show that pure Fe–14Cr–3W–0.2Ti–0.3Y body-centered-cubic phase was obtained at a reduction temperature of 1200°C for 3h. Using such powders the ODS steel was produced by spark plasma sintering (SPS) technique. The energy dispersive spectrometry mapping and transmission electron microscopy results indicate that the oxide particles of Y2Ti2O7with an average size of 55nm and particle number density of 3.2×1019m−3are homogeneously dispersed in the steel matrix. The tensile strength and uniform elongation of the steel that was SPS sintered and mechanically–thermally treated at 1100°C under a uniaxial pressure reach 1070MPa and 15%, respectively.
