摘要：
An experimental method for quantitative evaluation of the temperature effect on crack growth rate in low-alloy steels for the cast casings of stationary steam turbines of thermal power stations operating under long-term. and cyclic loading conditions is described. Practical use of the method is illustrated by a crack strength analysis of 15Kh1M1FL-grade steel, the material of a check valve of a 160 MW steam turbine with a service life of 110 thousand hours.
