Isothermal Recrystallization Behavior of Cold-deformed Martensite in an Ultra-low-carbon Microalloyed Steel
One of the most promising ways to produce a grain-refined microstructure in some steel materials is the thermomechanical processing route of subcritical recrystallization annealing of a cold-deformed martensite structure. In the present study, the microstructural evolutions and the associated recrystallization kinetics under various subcritical annealing heat treatment conditions are explored i...
متن کاملProcess modeling of microalloyed steel for near net shape casting
Strip casting is an emerging technology for flat products; it is based on the concept of near-net shape casting; it holds potential for substantial energy saving and reduction in environmentally undesirable emission. In conventional thermo-mechanical processing, the pinning pressure due to the effects of Nb and NbC on boundary mobility is used to advantage to retard static recrystallisation and...

متن کاملImage-based Bolt-loosening Detection Technique of Bolt Joint in Steel Bridges
This paper presents a novel bolt-loosening detection technique using image information of bolted joints in steel bridges. Firstly, existing bolt-loosening detection techniques are reviewed and their benefits and limitations are analyzed. Secondly, a bolt-loosening detection algorithm using image processing techniques is newly proposed for bolted joints in steel bridges. It consists of 3 steps: ...
متن کاملanisotropy in microalloyed s355n steel
thermomechanical control process steel produced by rolling has a significant anisotropy. the elongated grains and inclusions formed during hot rolling of ferrite and low carbon hsla steels directly influence the anisotropy of the steel’s mechanical properties as a result of microstructural anisotropy. the present research deals with this anisotropy, and particular attention has been paid to the...
