Structural Uses for Ductile Ordered Alloys. Report of the Committee on Application Potential for Ductile Ordered Alloys

摘要

The unique mechanical properties of ordered alloys that make them attractive for structural applications are described. A major difficulty with these alloys has been a lack of ductility; however, in recent years several methods of ductility improvement have been developed. These techniques are discussed. Current research efforts worldwide are reviewed, and it is concluded that the U.S. effort, although substantially smaller than it was 15 years ago, is yielding the most significant progress in the development of ductile ordered alloys. A number of possible generic applications are suggested for the newly developed ductile ordered alloys, including applications in gas turbine engines, rocket propulsion systems, and space power systems. Areas where additional engineering data are required about these alloys are identified and a phased program of data acquisition is recommended. It is emphasized that there is a great need for materials processing information. Areas for scientific research also are identified. Finally, it is concluded that the properties of the newly developed ductile ordered alloys appear to be sufficiently promising to warrant a coordinated program for the application of these alloys to be undertaken.
