Abstract:
The mechanical properties and the resistance to oxidation were determined for 304 stainless steel joints brazed with 61% Ni-39% In, 65% Ni-17% Cr-9% In-9% Si, 33% Ni-33% Cr-17% In-17% Ge, and 35% N-24% Cr-26% In-15% Ge filler alloys. The special technique developed for brazing these joints involved: (1) a method of preparation of the alloy so that a homogeneous and desired composition was available to fill the joint capillary, and (2) a method of volatilizing the melting point depressant which avoided the difficulty of boiling, while still obtaining sufficient volatilization to provide the required higher remelt temperature and good high-temperature properties. The highest shear strength was exhibited by the 65% Ni-17% Cr-9% Si alloy. The oxidation resistance of all joints was excellent. Joints brazed with the 61% Ni-39% In alloy showed considerable signs of oxidation after exposure to the open air for 500 hr at 1600 F.
