Damageafaility of Steel 25Kh1M1FA under Long-term Loading at Elevated Temperatures

The kinetics of damage accumulation in steel 25Kh1M1FA under long-term loading has been studied. The limiting state of material preceding fracture with different levels of normal stresses at the temperature of 500°C has been determined in the assessment by the coefficient of homogeneity m. The obtained data make possible using the LM-hardness test method to evaluate the current state of materials under long-term static loading at elevated temperatures. The procedure enables one to predict residual lifetime while using the limiting values for coefficients of homogeneity under given thermomechanical loading conditions.
