Abstract
The chemical stabilities of the synthesized and isolated phases, TiC, TiN, Ti(C,N), Ti4C2S2, (CrxFe1-x)23C6, (CrxFe1-x)7C3, Mo2C, MnS, (CrxM n1-x)S, were estimated in pickling media: nitric acid + hydrofluoric a cid, nitric acid, hydrochloric acid and potassium permanganate + sodiu m hydroxide, and in high temperature water, 513 K, for 3.6-720 ks. Som e of the tested pickling solutions do not dissolve or only partially d issolve titanium-containing phases isolated from Ti-stabilized austeni tic stainless steels. Sulphide phases isolated from stabilized stainle ss steels are much more stable in high temperature water in comparison with phases isolated from unstabilized stainless steels. Chromium car bide phases do not undergo any significant changes in high temperature water.
