酸化物分散強化型超合金

Mechanical alloying as a practical technique for producing ODS superalloys has evolved into a commercial scale production process. Alloys made by this method have the ability to retain long term creep strength and corrosion resistance at high temperatures.The thermomechanical working is optimized to obtain the most appropriate final grain size and morphology for each alloy and product form. A special moving zone annealing furnace has been developed for achieving a highly elongated grain structure in the turbine blade material INCONEL MA 6000. Forming, joining, and forging techniques have also been established for ODS superalloys to allow their use in a wide range of aerospace and industrial applications.The present and future ODS superalloys will offer the opportunities for increased thermodynamic efficiencies, better fuel utilization and greatly extended service lives for existing and advanced high temperature plants.
