DOI: 10.1016/j.tafmec.2017.05.023
Abstract: Abstract The effect on notch toughness of residual stresses introduced by pre-deforming double edge notched tensile specimens of the high-chromium reduced activation tempered martensitic steel F82H-mod was investigated. Residual elastic strains/stresses were introduced by pre-deformation… read more here.

DOI: 10.1080/09603409.2017.1389441
Abstract: Abstract Creep strength enhanced ferritic steels contain 9 to 12% Cr and were developed to exhibit excellent high temperature properties. These should be achieved when the microstructure exhibits a tempered martensitic matrix containing a substructure… read more here.
