This report presents information dealing with the oxidation of nickel- and cobalt-base superalloys. All of the superalloys will oxidize at high temperatures when oxygen is present in the enveloping atmosphere. The rate of oxidation depends upon alloy composition, temperature, oxygen concentration, oxides formed, diffusion rates of the metals in both base metal and oxide, diffusion rate of oxygen in the oxide, solubility of oxygen in the matrix, and a host of other variables. The effects of oxidation can be beneficial or they can be harmful. The first section of this report deals with the fundamentals of the oxidation of Ni-Cr and Co-Cr alloys. Subsequent sections discuss general surface oxidation, intergranular oxidation, other subsurface oxidation, and the effect of stress on the rate of oxidation. Numerous specific alloys are mentioned in the report; as an aid to the reader, the appendix contains an alloy index of the alloys mentioned in the report along with the compositions of the alloys, and the pages on which mention of the alloys is made.

Download Oxidation of Iron-, Nickel-, and Cobalt-base Alloys Book in PDF, ePub and Kindle
Iron-, nickel-, and cobalt-base superalloys, starting from the compositions Fe-20Cr, Ni-20Cr, and Co-(20 to 25)Cr, have been developed along fundamentally different routes dictated mainly by differing compositional requirements in the search for increased high temperature strength. In Ni-Cr alloys, for example, chromium content has been decreased gradually, and the aluminum content increased to the extent that the alloys now are basically Ni-Cr-Al alloys. In the review current data relating to the oxidation of the relevant pure metals and their binary and ternary alloys are examined first, and then data on oxidation of the more complex engineering alloys are considered. The oxidizing atmosphere is assumed to be oxygen or air, but the mechanisms described generally are applicable to other oxidizing atmospheres. (Author).

Download Understanding the Roles of the Strategic Element Cobalt in Nickel Base Superalloys Book in PDF, ePub and Kindle
The United States imports over 90 percent of its cobalt, chromium, tantalum and columbium -- all key elements in high temperature nickel-base superalloys for aircraft gas turbine disks and airfoils. NASA, through joint government/industry/university teams, has undertaken a long-range research program (COSAM - Conservation of Strategic Aerospace Materials) aimed at reducing or eliminating these strategic elements by examining their basic roles in superalloys and identifying viable substitutes. This paper discusses research progress in understanding the effects of cobalt and some possible substitutes on microstructure, mechanical properties, and environmental resistance of turbine alloys.

Download Superalloys 2012 Book in PDF, ePub and Kindle
A superalloy, or high-performance alloy, is an alloy that exhibits excellent mechanical strength at high temperatures. Superalloy development has been driven primarily by the aerospace and power industries. This compilation of papers from the Twelfth International Symposium on Superalloys, held from September 9-13, 2012, offers the most recent technical information on this class of materials.
