RISStainless Steels With Improved Oxidation Resistance for Recuperators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: New materials are being evaluated to replace type 347 stainless steel in microturbine recuperators operating at higher temperatures in order to increase the efficiency of the microturbine. ...
High-Temperature Performance of Cast CF8C-Plus Austenitic Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Covers and casings of small to medium size gas turbines can be made from cast austenitic stainless steels, including grades such as CF8C, CF3M, or CF10M. Oak Ridge National Laboratory and ...
Comparison of Recuperator Alloy Degradation in Laboratory and Engine Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to increase the efficiency of advanced microturbines, durable alloy foils are needed for their recuperators to operate at 650–700°C. Prior work has demonstrated that water vapor ...
Overview of Creep Strength and Oxidation of Heat-Resistant Alloy Sheets and Foils for Compact Heat Exchangers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Oak Ridge National Laboratory (ORNL) has been involved in research and development related to improved performance of recuperators for industrial gas turbines since about 1996, and in improving ...
Evaluation of Alumina-Forming Austenitic Foil for Advanced Recuperators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A corrosion- and creep-resistant austenitic stainless steel has been developed for advanced recuperator applications. By optimizing the Al and Cr contents, the alloy is fully austenitic for creep ...
