Strain dependent rate equation to predict elevated temperature flow behavior of modified 9Cr-1Mo (P91) steel

▶ Constitutive analysis is performed on hot compression flow data for P91 steel. ▶ The data is examined in terms of modulus, lattice and pipe diffusion coefficients. ▶ P91 steel obeyed rate equation ε˙/DL =constant [sinh(αLσ/G)]nh; αL, Ah, nh were strain dependent. ▶ Deviation in prediction was obse...
