Abstract

Creep rupture stresses at temperatures between 723-923 K have been estimated at a rupture life of 2.63×105 h for mod. 9Cr-iMo steel, using short-term tests data. Larson-Miller Parameter (LMP) and artifical neural network (ANN) approaches have been employed for extrapolation. The results are compared with extrapolated RCC-MR code data.
