- Simulation on Flow Field and Mixing Phenomenon in Single Snorkel Vacuum Degasser
Dian-Qiao Geng, Xin Zhang, Xing-An Liu, Ping Wang, Hai-Tao Liu, Hong-Min Chen, Chuan-Min Dai, Hong Lei and Ji-Cheng He
Article first published online: 17 SEP 2014 | DOI: 10.1002/srin.201400092
Flow field and mixing phenomenon in single snorkel degasser with ladle bottom blowing has been investigated by numerical method. The results show that the flow field inside the single snorkel vacuum degasser can be optimized in order to achieve higher recirculation rates and smaller mixing times, which are important to refining.
- Research on the Improvement Effect of High Tension on Flatness Deviation in Cold Strip Rolling
Xiao-chen Wang, Quan Yang, Zheng-yi Jiang and Jin-wu Xu
Article first published online: 17 SEP 2014 | DOI: 10.1002/srin.201400048
A roll-strip-tension coupling model with both accuracy and efficiency is established for cold rolling process with tension. Then the self-correction effect of front tension and the attenuation effect of back tension on flatness deviation are analyzed by the calculation results of the model, and corresponding quantitative correction coefficient and attenuation coefficient are obtained.

The austenite phase of duplex stainless steels (DSSs) is always considered to undergo nearly no phase transformation or precipitation upon annealing. The ferrite phase, on the other hand, is always regarded as the active transforming/precipitating phase. However, it's been found that if DSSs are plastically deformation and annealed between 900 and 1050°C, then the situation will be totally opposite.
- Physical Simulation of the Flow Field in a Vertical Twin Roll Strip Caster – A Water Model Study
Arnis Pelss, Antje Rückert and Herbert Pfeifer
Article first published online: 17 SEP 2014 | DOI: 10.1002/srin.201400150
The visualization of the flow inside the pool of a twin roll strip caster is important for the process. In this study, the flow is systematically investigated for different volume flow distributions in a full scale water model. Therefore the particle image velocimetry method and video analysis are used to determine the main flow patterns.
- Influence of Bainite Morphology on Ductile Fracture Behavior in a 0.4C-CrMoNi Steel
Navid Saeidi, Fakhreddin Ashrafizadeh, Behzad Niroumand, Mohammad Reza Forouzan and Frederic Barlat
Article first published online: 11 SEP 2014 | DOI: 10.1002/srin.201400155
SEM analysis is involved in studying ductile fracture mechanism in upper and lower bainitic steels. Detailed microstructural analysis reveales that cracking and interface decohesion of Al2O3 inclusions at lower strains and decohesion of cementite/ferrite matrix interfaces at higher strains are the main void nucleation mechanisms. Void growth behavior is also modeled. Moreover, final fracture mechanisms are examined and cleared in both steels studied.
