A vortex-shaped segregation was observed in low-speed samples while a banded structure with channel segregation was found in high-speed samples. The types and shapes of internal macro-segregation changed with different casting speed. From experimental results, larger segregation area was found in samples with high Mg and higher casting speed which matched the simulation results. Besides, the center layer of the cross-section was calculated to have lower cooling rate and higher deformation while the side layer was confirmed with a higher cooling rate.Īs one of the most widely used alloying elements for Al alloys, the effect of Mg element on the macro-segregation behavior of twin-roll cast Al alloys was investigated. Furthermore, higher casting speed caused the less contacting time between the roll and melt which delayed the cooling process and resulted in more segregation during the TRC process. According to the calculated results, freeze range increased and heat transfer coefficient decreased with the increasing Mg concentration which both indicated that more segregation can be expected from high Mg alloys. Specific points along the thickness direction were selected to track the local strain and liquid fraction during the TRC process. The effect of casting speed on the temperature and liquid fraction distribution was discussed. The temperature and liquid fraction distribution of Al alloys with various Mg concentration from 0.5% to 5% were investigated based on the thermodynamic properties calculated using JMatPro program.

Therefore, studies on the formation mechanism of different types of segregation and how to reduce segregation are still necessary.įEM simulation program DEFORM was used to predicted the solidification behavior during the twin-roll casting of Al alloys. Internal macro-segregation which is usually located in the center layer of the TRC strips cannot be completely removed by thermomechanical process after the initial solidification.
Despite all the advantages, the segregation forms during the TRC process is apparently harmful. Twin roll casting (TRC) is a continuous casting method which allows the fabrication of strips directly from melt which helps to decrease the fabrication cost and increase the productivity. However, the high fabrication cost compared to conventional steel materials is the main obstacle for wider application. 신광선.Ībstract Since Al has a low density and high specific strength along with sound corrosion resistance, the Al alloys have a great potential of application as structural materials in various industries.
