MANUFACTURING RESEARCH. BRAZING ALLOYS, HIGH TEMPERATURE OPERATING, DEVELOPMENT OF
GENERAL DYNAMICS CORP FORT WORTH TX
General flow, wetting and fillet forming characteristics of brazing alloys on base-metal alloys, with core sections of 17-7 PH stainless steel and M252 alloy were studied. Additional investigation was made of the promising base metal-brazing alloy combinations to determine their resistance to salt spray corrosion and 1250 F oxidation. Metallographic examinations were made to determine the amount of alloying of the brazing alloy with the base-metal and the extent of the brazing alloy diffusion into the base metal. The following base metal-brazing alloy combinations appeared to warrant further investigation PH 15-7 Mo - 24Pd, 56.2Ni, 9.8Cr, 10Si 422M - Coast 4271E, - J 8102, - 24Pd, 56.2Ni, 9.8Cr, 10Si, - J 8102 Inconel 700 - Coast 4271E M252 - J8205, - 24Pd, 56.2Ni, 9.8 Cr, 10Si GE 1610 - J8205, - J8101 - J 8100, - Solabraz IX1.
