Book Description
Various alloying additions have been discovered which render unalloyed chromium much less susceptible to low-temperature embrittlement as well as to nitridation in air at elevated temperatures. These include additions of the Group IIIA metals, magnesia, and carbides based on the Groups IVA and VA metals. Of these additions, only the carbides contribute significantly to the hot strengthening of chromium. The combination of selected carbides and solid-solution-strengthening elements such as tungsten, molybdenum, and/or tantalum, has resulted in experimental alloys which retain useful strengths at temperatures through 1316 C (2400 F). These high strengths are achieved at some sacrifice in the low-temperature ductility of chromium. Also, despite the improvements afforded in the oxidation and nitridation resistance of chromium through alloying, no alloys are available which are capable of service in long-time exposures in air above 982 C (1800 F) without suffering some property degradation.

Development of Partially Volatile Brazing Filler Alloys for High-temperature Application and Resistance to Oxidation

Book Description
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. (Author).
