The aim of this work was to summarise XRD investigations performed after the tests carried out in steam oxidation conditions in the temperature range 700‒800°C for 3000 hours. In this work, two solid-solution strengthened alloys; Haynes® 230®, 617 alloy and two (γ’) gamma-prime strengthened alloys; 263 and Haynes® 282® and high alloyed steels rich in Cr: 309S, 310S and HR3C were exposed. The phase analyses were carried out using two techniques; Bragg-Brentano (BB) geometry and geometry of constant angle called grazing incidence α = 1° and α = 3°.
