PRELIMINARY EVALUATION OF FOUR COLUMBIUM BASE ALLOYS FOR COATING CAPABILITIES AND MECHANICAL PROPERTIES AT ELEVATED TEMPERATURES. ADDENDUM I. STRUCTURAL BRAZING AND ALUMINIDE COATING,

Abstract

The evaluation of titanium-brazed niobium base alloys coated with Nb disilicide was completed. These tests indicated catastrophic embrittlement of the braze joint area. Preliminary testing of brazed joints protectively coated with aluminide and tested at 2600 F in air indicated retention of basic Nb alloys base metal properties without any adverse effect (decline of values) or embrittlement on the braze joint area.
