Abstract
The article presents the results of investigation of thermal expansion of 16Kh12V2FTaR steel in the temperature range 20–1000 ºС. Measurements were carried out by dilatometric method with the error (1.5–2)×10−7 K−1. The temperature dependences of thermal coefficient of linear expansion of steel have been obtained in ferrite-martensite and ferrite-perlite states, and reference tables have been calculated. Influence of samples cooling rate on martensite phase formation is shown.
