Currently there is a great interest in developing nickel base alloys with fine and uniform dispersion of stable oxide particles, for high temperature applications. It is well known that the high temperature strength and stability of an oxide dispersed alloy can be greatly improved by appropriate thermomechanical processing, but the mechanism of this strengthening effect is not well understood. This investigation was undertaken to study the dislocation substructures formed in beryllia dispersed nickel alloys as a function of cold work both with and without intermediate anneals. Two alloys, one Ni-lv/oBeo and other Ni-4.5Mo-30Co-2v/oBeo were investigated. The influence of the substructures produced by Thermo-Mechanical Processing (TMP) on the high temperature creep properties of these alloys was also evaluated.

Abstract Haynes 625SQ alloy is a modification of Haynes 625 alloy (see Alloy Digest Ni-354, January 1988) with tighter controls on chemistry and a finer grain size for fatigue resistance up to 680 deg C (1250 deg F). This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties as well as fatigue. It also includes information on high temperature performance as well as heat treating. Filing Code: Ni-612. Producer or source: Haynes International Inc.
