Two Al-Mn-Zr alloys produced by twin-roll casting having almost the same chemical composition except for the content of zinc (0.10 and 1.66 wt.%, respectively) were investigated. Precipitation reactions during two-step annealing were examined by means of electrical conductivity and differential scanning calorimetry. Furthermore, SEM quantitative particle analysis, energy dispersive spectroscopy, and electron backscattered diffraction were carried out. The results show that 1.1 to 1.8 wt.% of zinc enters into constituent Al15(Mn,Fe)3Si2 phases and that zinc improves nucleation of small Al(Mn,Fe)Si particles, 20 to 100 nm in size, which is beneficial for the recrystallization resistance of the alloy.K e y w o r d s : Al-Mn-Zr alloys, Zn addition, microstructure, SEM quantitative particle analysis, phase analysis

“…Along with the longitudinal and transverse cracks, the other types of defects associated with the strip surface are surface bleeds [63], buckling [3], microsegregation [65], banded structure [66], edge cracking and ripple defects [67], and so forth which are formed due to low casting speed.…”

Nowadays near-net-shape casting technology is an important area of research in the iron and steel industry. Among different kinds of near-net-shape casting process, twin-roll casting process has received much attention among researchers. Twin-roll casting (TRC) has been the subject of extensive research, not only to develop the technology but also to achieve an understanding of microstructural evolution and to produce quality strips. The main issues concerning the design and operation of twin-roll casters are metal-mold heat transfer, metal delivery system, and their possible effects on the solid shell formation and characteristics of the strips. The present review gives an idea about the process aspect, modeling, and quality issues in vertical twin-roll strip casting process and helps to improve the design of twin-roll strip caster.

“…In 2000, during twin roll casting of aluminum alloys, various macroscopic defects such as surface bleeds and deformation segregates were observed by Yun [6]. In 2005 and 2006, Gras [7] and Forbord [8] investigated also respectively twin roll casting of aluminum alloys and found the micro defects formation. With the development of computer, combination of simulation and test become an effective method for TRC.…”

6181 aluminum alloys sheets were produced by two-roll casting with electric current pulse and magnetic fields, and the microstructures were observed. The experimental results show that application of composite fields (ECP and EM field) during TRC process refines the microstructures of sheets more evenly and effectively by comparison with individual application of ECP or EM field. For visually explaining the phenomenon, the distribution and amplitude of the magnetic induction intensity B and electromagnetic force F were obtained by numerically simulated. In addition, an obvious improvement of tensile strength by physical fields was measured. But the maximum elongation was from action of magnetic field and reached 10.9%.
