Large gradients ods aluminum content FeCrAl alloy sheet material, preparation method and application

Large gradients aluminum content preparation ODS FeCrAl alloy sheet material, the present invention is to solve the conventional metallic thermal protection system of the honeycomb structure laminates problem oxidation resistance and weldability can not be balanced. As follows: The ingot containing material into a water-cooled copper crucible, yttrium oxide or yttrium oxide ceramic powder into the column another water-cooled copper crucible, the superalloy substrate was heated to 650-1000 ℃, heat; ingot containing material was evaporated and yttria or yttria ceramic ingot powder was naturally cooled to 50 ℃, that is, too. Good oxidation resistance of the material of the present invention, one side of the antioxidant, the other side of easy welding. Preparation FIELD This invention is a thermal protection system metal honeycomb structure vertical ply material.
