- Effect of Mg Addition on the Characterization of γ-α Phase Transformation During Continuous Cooling in Low Carbon Steel

The influences of Mg on the phase transformation and mechanical properties in low carbon steel were investigated, and the effects of Mg on the pearlite characteristic and the formation of bainite phase have been discussed. It is concluded that the pearlite transformation is delayed and the bainite transformation is promoted by adding 0.0026 %Mg.

The requirement of new steel grades for auto-body in order to reduce weight, save energy and improve safety leads to the production of advanced steel grades. The study analyses the flow curves of DP and TRIP steels through a strain hardening prediction . The chosen interpolating formula shows a very effectively reproduction of both the stress-strain curve and its derivative.
- Numerical Investigation of Fluid Flow and Heat Transfer Phenomenon Inside a Single Strand Tundish of Slab Caster

The current work investigates different aspects of well-shaped bottom tundish. The results obtained shows that well-shaped bottom tundish produces better performance as compared to tundishes having flat bottom. It is also noticed that throughput effect(between 2 and 3.5 tonnes min−1) on flow characteristics of this tundish will not be significant and will only lead to change in theoretical residence time.

Micromechanics based RVE models were applied to predict failure occurrences in various DP microstructures by considering plastic strain instability. Influences of morphologies and properties of constituent phases on localization were discussed with regard to governing stress states. Higher strain gradients in DP microstructures with lower MPF could lead to local high work-hardening rates that resulted in delayed localization.
- Heat Transfer Symmetry of the Strip Surface Due to Agroup Oblique Slot Jet Impingement After Hot Rolling

The heat transfer symmetry of single group oblique slot jet impingement for the flow and geometric parameters is investigated numerically using the CFD code. The numerical calculations are performed for 96 combinations, and the results provide a certain reference for improving the stability and uniformity of micro heat transfer during the high strength cooling process.
