Abstract

The influence of cold wire drawing on the structure of a pearlitic steel containing 0.7 wt% of carbon and subjected to a strain of approximately 3.5 has been studied. The as-deformed microstructure is very fine, with an interlamellar spacing close to 20 nm, and contains high internal elastic strains. The main result concerns the cementite phase which undergoes a dissolution, at least partial, during wire drawing. The proposed interpretation of the cementite dissolution is based on the destabilization of this phase due to the increase of its free energy arising from thinning of cementite lamellae and creation of slip steps during wire drawing. Post-deformation annealings lead to restoration of the phase equilibrium by precipitation of the cementite, and also to recovery of the defects, mainly interfaces, stored in the microstructure during deformation.

Effect of interlamellar spacing on cementite dissolution during wire drawing of pearlitic steel wires

Journal Article Nam, W; Bae, C; Oh, S; ... - Scripta Materialia

Cold drawing is an effective process to increase the strength of fully pearlitic steels with an acceptable level of ductility. Microstructural changes and deformation behavior of the pearlite during wire drawing are closely related to the initial microstructure of the pearlite. The main features of the changes while increasing drawing strain are a progressive alignment of lamellae along the drawing axis, a reduction of interlamellar spacing and a thinning of the lamellar cementite. Likewise, the behavior of the cementite dissolution would be influenced by microstructural features of the pearlite before drawing such as interlamellar spacing, colony size, etc. However, itmore »« less

Evolution of cementite morphology in pearlitic steel wire during wet wire drawing

Journal Article Xiaodan, Zhang; Godfrey, Andrew; Hansen, Niels; ... - Materials Characterization

The evolution of the cementite phase during wet wire drawing of a pearlitic steel wire has been followed as a function of strain. Particular attention has been given to a quantitative characterization of changes in the alignment and in the dimensions of the cementite phase. Scanning electron microscope observations show that cementite plates become increasingly aligned with the wire axis as the drawing strain is increased. Measurements in the transmission electron microscope show that the cementite deforms plastically during wire drawing , with the average thickness of the cementite plates decreasing from 19 nm ({epsilon} = 0) to 2 nmmore »« less

Mechanical and thermal stability of heavily drawn pearlitic steel wire

Book Aernoudt, E; Delrue, H; Van Humbeeck, J; ...

Having interlamellar spacings on the nanometer scale, there is no doubt about considering heavily drawn pearlitic steel wire as a nano-layered material. This extremely fine structure is of great technical importance: indeed, as the interlamellar distance determines the onset of plastic flow, the wire can be brought to a tensile strength beyond 4,000 MPa and is therefore one of the strongest materials on the market nowadays. At extremely large strains (well beyond {var_epsilon} = 4) and/or at moderate temperatures, the pearlitic steel loses its strength. Several possible failure mechanisms, like fragmentation of the cementite or thermal and strain-induced cementite dissolution,more »« less
Neutron diffraction measurement of the residual stress in the cementite and ferrite phases of cold-drawn steel wires

Journal Article Van Acker, K; Van Houtte, P; Aernoudt, E; ... - Acta Materialia

The residual stress state in both the cementite and ferrite phases of cold-drawn pearlitic wires has been measured by neutron diffraction. The phase microstress in the axial direction is obtained. It is found that the cementite lamellae are subjected to a high tensile stress, up to 2,000 MPa, after cold drawing. Measurements on etched wires showed that the phase microstress is nearly constant with the distance to the wire axis. Combination of these data with complementary X-ray diffraction measurements on the ferrite determines the response of each phase to the macrostress or an applied stress. Additionally, the peak broadening andmore »« less

The FEM Simulation Of Cementite Lamellas Deformation In Pearlitic Colony During Drawing Of High Carbon Steel

Journal Article Milenin, Andriy; Muskalski, Z - AIP Conference Proceedings

In paper the wire drawing processes was investigated in two levels - steady-state solve using the 2-dimensional rigid-plastic finite element method (macro-level) and modeling of a microstructure change (micro-level). In macro level the joint deformation-temperature problem was considered. In micro-level the process of deformation of representative volume element - RVE was considered. The pearlitic colony deformation and orientation of cementite lamellas change in RVE was modeled with help of a FEM. The micro-level model to rigid-plastic finite element code was implemented. The experimental data of microstructure and orientation of cementite lamellas change was compared with results of a simulations. Themore »« less
