The results are given on the long-term high-temperature indentation testing steel grades, on plotting the creep diagram in the strain—time coordinates during loading at temperatures up to 700°C. For structural steel 15Kh2NMFAA, widely used in the power engineering to manufacture equipment operating at high temperatures, the relationships are obtained linking the creep rate with the temperature at a constant initial stress.

The corrosion rate of AlTi0.1 modified with 0.01–0.5 wt % of an alkali metal decreases by 10–20%.
