Фазовые превращения в материалах энергетического машиностроения

Abstract

The article considers results of structural transformations in nickel allows of various alloying levels, including those with higher chromium content, depending on conditions of heat treatment and ageing in laboratory conditions or during operation, structural transformations on the surface, including formation of oxide phases under different conditions (depending on temperature, time and environment), phase reactions in steels of various alloying levels depending on temperature and time, phase transformations in coatings of gas turbine blades.
