The effects of different percentages of excess oxygen and titanium on the mechanical property and microstructure of 9Cr-ODS steel were investigated in the wide range of excess oxygen from 0.03wt% to 0.18wt%. It was shown that the controlling of the atomic ratio between excess oxygen and titanium (x in TiOx) around 1.0 is indispensable for the high-temperature strength improvement.
