Comparative status of columbium--tungsten composites for gas turbines

  • 1. International Harvester Co., San Diego, CA

Description

Synthesis of composite materials for use in gas turbines above 20000F constitute a challenging problem. Requirements for these materials are reviewed and current material development approaches are described. Comparison of properties and analysis of test data show that the niobium-tungsten composites are closest to application. The strengths and weaknesses of this composite are discussed and recommendations made for critical application. The optimum temperature range for this material appears to be 2000 to 26000F. (U.S.)
