Isochronous stress versus strain curves for normalized-and-tempered 2 {1/4}Cr-1Mo steel
Conference
·
OSTI ID:484609
Tensile and creep data were collected for normalized-and-tempered 2 {1/4}Cr - 1Mo steel and used to construct isochronous stress versus strain curves to 100,000 h for temperatures to 566{degrees}C (1050{degrees}F). A plasticity equation was selected that normalized the flow curves to the yield strength, and a creep equation was formulated that included a parabolic primary creep term and a linear term. Due to the early initiation of tertiary creep in the normalized-and-tempered steel, the isochronous curves were limited to 1% total strain.
