In　this　paper,　the　acoustic　microscope　is　used　to　study　the　acoustic　propagation　characteristics　and　quality　evaluation　methods　of　the　oxide　dispersion　strengthened　ferritic　steel,　which　is　the　basic　industrial　material　in　the　future　nuclear　energy　field.　Time　domain　analysis　and　frequency　domain　analysis　methods　were　used　to　get　the　elastic　constants　of　oxide　dispersion　strengthened　(ODS)　ferritic　steel　samples　with　different　chromium　contents　in　comparison　experiments.　The　experiment　results　show　that　both　of　the　ultrasonic　testing　methods　are　applicable　to　determine　the　elastic　properties　of　this　material,　and　the　compactability　of　the　formed　materials　can　be　detected　using　the　velocity　comparison.　This　technology　provides　a　feasible　method　for　the　studies　of　the　mechanical　property　characterization　and　quality　testing　technique　of　ODS　ferritic　steel　materials.
