Abstract
The article gives the review of the influence of various alloying components and impurities on chromium and chromium-base alloys attributes and also the review of the production methods of these alloys. The metalo-physical and physico-chemical principles of the production of dispersion-strengthed alloys are examined. The coagulation of dispersed particulates during heating of metal and hot metal endurance “Ostwald Maturity” is examined. It was found that those processes are linked with the excessive free energy (Gibbs energy) reduction. The conclusion about the necessity of thermodynamical estimation of pointed out processes was done and the results are described.
