Large high aluminum content ods ferritic alloy sheet material and method

Large high aluminum content of the iron alloy sheet of ODS ferrite material and method, 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. The present invention is a material thickness of 0.01-0.3mm, a diameter of 1000mm, weight percent of the sheet by the component by 15.0% -20.0% Cr, 10.0% -15.0% Al, 0.3% -0.6% Y2O3 and a balance of Fe. 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. Aluminum alloy sheet material of high ODS ferrite content of the present invention prepared by the method (10.0wt% -.. 15.0wt%), good oxidation resistance (weight 1100 ℃ 100h air oxidation by not more than 0.8mg / cm2). Preparation art metal honeycomb structure vertical ply material of the thermal protection system of the present invention.
