- Isothermal Crystallization Study of (2CaO · SiO2–3CaO · P2O5) Solid Solution in the 45 mass% CaO-30 mass% SiO2-20 mass% FeOt-5 mass% P2O5 System at 1623 K

The isothermal crystallization study of the (2CaO · SiO2–3CaO · P2O5) solid solution demonstrates that the phosphorus distribution ratio between the (2CaO · SiO2–3CaO · P2O5) solid solution and the liquid phase during the isothermal crystallization process is increased rapidly during the initial stage from 10 s to 60 s, then it reduces gradually; after 1800 s, it reaches to a steady value.

Integrated studies from theoretical analysis, laboratory experiments and field trial are conducted to optimize the mold flux for heat-resistant alloy containing Al and Ti. The results present modified mold flux with reduced melting temperature, good lubrication, and low crystalline fraction, promotes heat transfer which enhances thickening and strengthening of the initial shell, all of which contribute to improved slab quality.

Prediction of more than four ears in a cup drawing process can be successfully achieved by considering flexible combinations of two different yield criteria under the framework of Non-Associated Flow Rule. The use of Hill (1948) model for the yield function and Yld2000-2d for plastic potential is shown to lead to accurate prediction of up to eight ears at alow computational cost.
- Microstructure Evolution of a New Dual-Phase Steel via Multi-Pass Compression Deformation in the (α + γ) Region

Ferrite grain refinement was prominent at the initial pass deformation, and the average grain size reached 1.8 μm after the fifth pass deformation. The LAGBs continuously transformed into HAGBs with increasing strain, and their misorientation increases gradually, thus caused the occurrence of grain refinement. The main refinement mechanism is the DRX of ferrite at the later pass deformation.

Thermomechanical control processing (TMCP) of TRIP-assisted steels is introduced as a potential energy saving alternative to the common processing route of cold-roll and two-stage heat treatment process. The present research indicates that an outstanding balance of strength–ductility can be achieved through development of a multiphase microstructure when it is subject to a typical multi-stages cooling/deformation program followed by short bainitic holding.
