Pearlite phase transformation in Si and V steel
Metallurgical and Materials Transactions A, 1995 Systematic research has been undertaken on the effects of single and combined additions of vanadium and silicon on the phase transformation and microstructure of pearlitic steels. Both alloy additions were found to result in the formation of nonlamellar products in the vicinity of austenite grain boundaries in hypereutectoid compositions (0.77 to 0.95 ...

steel research international, EarlyView.Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...

Journal of Applied Crystallography, EarlyView.Modifications of the fundamental equation of X‐ray stress analysis are proposed that allow correction of the hoop and longitudinal stresses obtained from sin2ψ measurements on samples featuring an inhomogeneous surface topography. The formalism is verified by angle‐ and energy‐dispersive measurements performed on a ferritic steel sample with ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Modeling of Anisotropy Evolution in Pearlitic Steel
, 2013 In a pearlitic structure, large deformations lead to a re-orientation and alignment of cementite lamellae on the microscopic level. These changes in the microstructure of pearlitic steel under large plastic deformations inducesubstantial degrees of ...
