Abstract

An article and a method for forming the article are presented. The article includes a material comprising a metal matrix and a first population of particulate phases disposed macroscopically non-uniformly within the matrix. The particulate phases include an oxide phase. Further embodiments include articles, such as turbomachinery components, fasteners, and pipes, for example, and methods for forming the articles.

Description

technical field [0001] The present invention relates generally to nanostructured ferritic alloys. More particularly, the present invention relates to articles formed from nanostructured ferritic alloys having a non-uniformly distributed dispersion and methods of forming the same. Background technique [0002] Gas turbines operate in extreme environments, subjecting turbine components to high operating temperatures and pressures, especially those in the hot zone of the turbine. In order for turbine components to withstand these conditions, they are manufactured from materials that can withstand these harsh conditions. When material limits are reached, one of two methods is routinely employed to maintain the mechanical integrity of the hot zone components. One way is to use cooling air to lower the effective temperature of the component. The second method is to increase the component size to reduce the pressure. However, these methods reduce the efficiency of the turbine a...
