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 ...

Advanced Heat Treatment of Pearlitic Rail Steel
Materials, 2023 The aim of this research is a systematic investigation of heat treatments of 60E1 profile rails made of steel R350HT, which would ensure the properties required by the standard EN 16273. Additionally, it presents a concept of cooling rails on a semi-industrial station, which will make it possible to obtain the desired properties. The dilatometric tests
