On the interface of the Cu-Al composite plate from horizontal continuous casting,the eutectic microstructure layer thickness ac-counts for more than 90%of the total interface thickness,and the deformation in rolling forming plays an important role in the quality of the composite plate.The eutectic microstructure material on the interface of the Cu-Al composite plate was prepared by changing the cooling rate of ingot solidification and the deformation in hot compression was investigated.The results show that when the deformation temperature is over 300℃,the softening effect of dynamic recrystallization ofα-Al is greater than the hardening effect,and uniform plastic deformation of eutectic microstructure is caused.The constitutive equation of flow stress in the eutectic microstructure layer was established by Arrhenius hy-perbolic-sine mathematics model,providing a reliable theoretical basis for the deformation of the Cu-Al composite plate.

To investigate the temperature distribution and solidification shell profile in a continuous casting process for round bars, transient mathematical models have been developed to describe the thermal process. Then Finite Element Method (FEM) has been applied to simulate the solidification process. Parameters including casting speed, casting temperature and cooling conditions have been analyzed. It is shown that different parameters have different influence on the thermal process and must be carefully controlled in continuous casting process. Finally, the simulated results are compared with the experimental ones.

The horizontal continuous casting process,the initial step in TP2 copper tubular processing,directly determines the microstructure and properties of copper tubular.However,the process parameters of the continuous casting characterize time variation,multiple disturbances and strong coupling.As a consequence,their influence on a casting billet is difficult to be determined.Due to the above issues,the common factor and special factor analysis of the factor analysis model were used in this study,and the casting experiment and billet metallographic experiment were carried out to diagnose and analyze the reason of the microstructure inhomogeneity.The multiple process parameters were studied and classified using common factor analysis,2 the cast billets with abnormal microstructures were identified by GT^(2) statistics,and the most important factors affecting the microstructural homogeneity were found by special factor analysis.The calculated and experimental results show that the principal parameters influencing the inhomogeneity of solidified microstructure are the primary inlet water pressure and the primary outlet water temperature.According to the consequence of the above investigation,the inhomogeneity of the copper billet microstructure can be effectively improved when the process parameters are controlled and adjusted.

The combination of electromagnetic field is applied in the horizontal Direct Chill(HDC)casting process to produce 3004 aluminum alloy ingot.The effect of combination of electromagnetic field on the ingot surface quality and inner structure was investigated by macro and micro-structure observation.The results show that the combination of electromagnetic field can improve the ingot surface quality and inner structure effectively.The thickness of segregation layer decreased with the application of combination of electromagnetic field.In addition,the combination of electromagnetic field can effectively improve the as-casting structure.Under the function of combination of electromagnetic field,coarse columnar grains transfer to fine equiaxed grains.
