Effect of atomic ordering on structure formation for a nickel alloy with high chromium content

1. Ordering treatment makes it possible to control the distribution and dispersion of strengthening phases in high-temperature nickel-chromium alloys with high chromium content, and this makes it possible to use the phase based on chromium as a strengthener in addition to γ′-phase. 2. Ordering heat-treatment is a promising method for affecting the strength and ductility characteristics of industrial high-temperature high-chromium alloys. As a result of high thermal stability of strengthening phases, after this treatment high values of long-term strength are achieved.
