The effect of hydrogen on the deformation of pearlite in steels [PDF]
, 2022 Abstract Hydrogen embrittlement in steel gas infrastructure is a serious challenge for the use of hydrogen energy for global decarbonization. Steel gas pipelines contain a significant fraction of pearlite, which consists of lamellar cementite in ferrite.

Low cycle fatigue simulation and fatigue life prediction of multilayer coated surfaces [PDF]
, 2010 This paper focuses on the simulation of low cycle fatigue (LCF) failures in highly loaded coated surfaces subjected to mixed rolling-sliding contact in dry conditions. The development of an advanced finite element (FE) model and creation of a unique user-

Evolution of crystallographic texture and material anisotropy effects resulting from uniaxial deformation for high-strength steels with high manganese content. [PDF]
J Appl CrystallogrThe present study investigates the deformation behavior of high‐strength steels and the associated evolution of material anisotropy. Particular focus is placed on the impact of crystallographic texture and intergranular strains on how residual stresses can be evaluated using X‐ray diffraction and the associated assessment of weld seams in the ...
