HIGH STRENGTH TUBULAR CATHODES FOR ELECTRON TUBES

摘要

Using fourteen (14) alloying elements, ten (10) alloying series with nickel were favestigated over selected composition ranges. The hot strengths of experimental alloys at cathode operating temperatures were evaluated by means of yield strength measurements. Results were found to correlate directly with shock tests performed on representative alloys mounted in a production 6AQ5 tube type.
