INVESTIGATION OF A CHROMIUM PLUS ALUMINUM OXIDE METAL-CERAMIC BODY FOR POSSIBLE GAS TURBINE BLADE APPLICATION

摘要

A metal-ceramic composition containing approximately 80 percent chromium plus 20 percent aluminum oxide (Al2O3) "by weight has been investigated for possible gas-turbine blade use. The results of modulus-of-rupture, thermal-shock, and blade-performance studies indicate that this material may have adequate thermal-shock resistance; however, the strength for the application appears marginal.
