A thermokinetic diagram of decomposition supercooled austenite R350LHT steel was constructed based on the results its dilatometric, metallographic and hardness analysis during continuous cooling in isothermal conditions. It found that at a rate 0.1 1 °C/s causes by pearlite mechanism. After lower rate, structure is coarser has (289 HV). This due to higher temperature range transformation, which...

Abstract The molecular dynamics (MD) simulation method was adopted to explore impact of interface chemistry on pearlite mechanical response Bagaryatskii orientation relationship between ferrite and cementite. By changing terminal surface types cementite at ferrite-cementite interface, this study analyzed influence peak stress plastic deformation behavior, as well strain transmission two phases ...

The article presents the results of analysis evolution defective substructure rail steel pearlite with lamellar morphology under deformation by uniaxial compression. strain hardening studied such has a multistage character. Deformation is accompanied fragmentation grains, which intensifies as degree increases and reaches 0.4 foil volume at ε = 50 %. Fragments formed in ferrite plates are separa...

This paper describes the relations between microstructure, mechanical properties, and electromagnetic behavior of carbon steel wires submitted to different thermomechanical treatments. The electrical resistivity bulk magnetic properties are determined through measurements down 2 K hysteresis loop measurements. In addition, domains imaged by force microscopy despite complex microstructures. main...

The mechanical improvement and "self-protection" properties are mainly needed to develop weather-resistant steel materials. In this study, A588 was given thermomechanical treatment (hot-rolling) followed by a quench-tempering process. is modified adding 1, 2, 3 wt% nickel the primary alloy. Steel made using hot rolling process at 750 ℃ for 1 hour with 70% thickness reduction. sample heat-treate...
