Physical Metallurgy and Physicochemical Behavior of High-Temperature Chromium Alloys. Part I. Impurities in Chromium, Disperse Strengtheningof Chromium Alloys

摘要

Information regarding the influence of alloying elements and impurities on the properties of chromium and its alloys and methods of producing such alloys is reviewed. The physical and physicochemical principles for the production of dispersely strengthened alloys are considered in detail. The strengthening of disperse particles on heating and holding the metal (Ostwald ripening) is discussed. These processes are associated with decrease in the excess Gibbs free energy. The need for thermodynamic assessment of those processes is established.
