Thermomechanical treatments of a 1050 pearlite steel
Metallurgical Transactions A, 1983A study of the microstructures and mechanical properties of thermomechanically treated 1050 steel has been carried out. The materials were first transformed to fine and coarse lamellar pearlite structures. These samples were reduced 75 pct in thickness by cold rolling, then heat treated at 780 °C (up-quenching) or 650 °C (annealing) for different ...

Modelling and prediction of thermal deformation behaviors in a pearlitic steel
, 2020To predict the thermal deformation behavior in pearlitic steel, the stress–strain data from hot compression tests on a Gleeble-1500D thermo-simulation machine, with the strain rate range of 0.001–1 s−1 and the deformation temperature range of 1223–1373 K,

Electropulsing of pearlitic steels
2016Electropulsing is a process characterised by the application of short duration (~100μs) electrical current pulses. The process is claimed to be capable of stimulating microstructure change in a variety of metals at low temperatures and energy levels. In this thesis, electropulsing is applied to examine its potential to produce nanostructured, strong ...

New insight into the dry rolling-sliding wear mechanism of carbide-free bainitic and pearlitic steel
Wear, 2019The comparison of wear resistance of bainitic and pearlitic steel is still a matter of controversy. In this study, the dry rolling-sliding wear behaviors of three types of pearlitic steel and one carbide-free bainitic rail steel have been investigated ...

Properties of pearlite-free steel with niobium
Metal Science and Heat Treatment, 19751. Pearlite-free steel alloyed with niobium has good resistance to brittle fracture — the ductile-brittle transition temperature determined from the work of crack propagationap=2 kg-m/cm2 is −100°. 2. The optimal niobium concentration is about 0.1%.

Atom probe microanalysis of a pearlitic steel
Metal Science, 1977AbstractA computer-controlled FIM/atom probe mass spectrometer has been used to measure the partitioning of alloying elements between the carbide, matrix, and interface regions of a commercial 0.8C-0.7Mn-0.3 wt.-%Si pearlitic steel, produced by a lead patenting process.

Strain-induced coarsening of ferrite lamella in cold drawn pearlitic steel wire
, 2020Strain-induced coarsening of ferrite lamellae in pearlitic steel wires during cold drawing was investigated. Experimental results demonstrated that the coarsening of ferrite lamellae was caused by strain-induced grain boundary migration.
