Journal ArticleDOI
Cold-drawn pearlitic steel wires
TL;DR: In this article, the microstructural evolution during progressive cold-drawing is studied and a consolidated view indicates that carbon-defect interactions play a major role in all aspects of the wire properties.
Journal ArticleDOI
Hydrogen embrittlement of prestressing cables
TL;DR: In this article, the authors simulated hydrogen embrittlement with ammonium thiocyanate media test and showed that three stages of the damage mechanism are identified with different acoustic activities.
Journal ArticleDOI
Role of drawing-induced residual stresses and strains in the hydrogen embrittlement susceptibility of prestressing steels
TL;DR: In this article, the authors analyzed the role of plastic strain in hydrogen embrittlement of prestressing steel and showed the necessity of considering it in hydrogen diffusion calculations, because stress-only assisted diffusion leads to dramatic underestimation of the hydrogen content.

Tensile Deformation Behavior of Duplex Stainless Steel Studied by In-Situ Time-of-Flight Neutron Diffraction
TL;DR: In this article, the anisotropic elastic/plastic properties of the duplex steel were simulated using a visco-plastic selfconsistent (VPSC) model that can predict the phase stress and the grain-orientation-dependent stress.

Elastoplastic deformation of ferritic steel and cementite studied by neutron diffraction and self-consistent modelling
Mark R. Daymond,H.G. Priesmeyer +1 more
TL;DR: In this article, a tensile specimen was machined from heat treated ferritic steel, with a small volume fraction of carbon in the form of cementite, and in situ measurements of the strain response of multiple hkl lattice planes to an applied uniaxial tensile load were made using neutron diffraction, to macroscopic plastic strains of around 3%.
Journal ArticleDOI
Interphase and intergranular stress generation in carbon steels
TL;DR: In this paper, the evolution of internal stress in high and low carbon steels with and without a reinforcing phase was investigated using neutron diffraction spectra acquired during tensile straining, and the results showed that in low carbon steel, the generation of intergranular stresses predominates, while in high carbon steel similar intergranularity stresses among ferrite grain families are superposed upon a large redistribution of stress between phases.
Journal ArticleDOI
In situ neutron diffraction during tensile deformation of a ferrite-cementite steel
TL;DR: In this article, a profile analysis of diffraction spectra was performed to identify microstrain related to dislocation density and block size, strength and workhardening of steel wire.
