Creep Rupture Behavior in Dissimilar Weldment between FB2 and 30Cr1Mo1V Heat‐Resistant Steel
International Journal of Photoenergy, Volume 2021, Issue 1, 2021., 2021 Creep rupture behavior of dissimilar weldments between FB2 and 30Cr1Mo1V heat‐resistant steel by multipass welding at 783 K (510°C) under different stresses (260 to 420 MPa) was researched. The fitted creep rupture exponent is 14.53, and the 10,000 h extrapolating strength values predicted by the power law and Larson‐Miller parameter show good ...
