AbstractA procedure based on Theta-methodology coupled with the knowledge of oxidation kinetics is envisaged for quantitatively assessing the effect of oxidation on creep curves.The procedure is based on the generation of a series of real constant-stress creep curves,at different stress and temperature levels,in inert atmosphere,where the effects due to oxidation are kept to a minimum level.Experimental Study of the Creep Lifetime of the 1.25Cr 0 Correlation between creep and hot tensile behavior for 2.25Cr-1Mo steel from 500 pdf creep behavior of 1cr0 5mo steel part 2#176;C to 700 pdf creep behavior of 1cr0 5mo steel part 2#176;C.Part 2 An assessment according to different parameterization methodologies Article
