Nonlinear ultrasonic measurements has been proposed to characterize the creep damage evolution of P92 martensitic ferritic steels at a temperature of 650 °C and stresses of 100 MPa and 115 MPa, respectively. The correlation of increase-decrease-increase between the ultrasonic nonlinearity and the creep strain was achieved for both sets of specimens. Considering the metallographic studies, nonlinear...
P92 martensitic ferritic steels are an attractive material for critical components in power industries due to the excellent creep property. However, these steels are usually susceptible to creep strength degradation during a long service period under the elevated temperature and pressure. Creep damage evaluation is of concern to quantitatively assess the remaining lifespan of the critical components...
