It has been found that developing innovative lightweight materials using a tandem twin roll-caster was possible. A two layered material, Al/Mg alloys as well as a three layered material, Al/Mg/Al alloys were fabricated in the present study. A high tensile Mg alloy which contains relatively high aluminum content (weight ratio of Aluminum was 9 to 12 percent) was used as a core material of the clad. It has already been shown that AZ121 which contains 12 percents aluminum has a tensile stress of the 420MPa, and a 0.2 percent proof stress of 380MPa. As a result of analysis of the cladded interface, there is a mixed layer composed of intermetallic compounds of 15micron meters in the interface. Also, intermetallic compounds Al3Mg2 as well as Mg17Al12 were detected by EDSD analysis. A 90 degrees bending test was performed to examine the connection of the different materials. It has been clarified that the interface could be successfully cladded, due to a result of 90 degrees bending test.

人们发现，使用串联双辊连铸机开发创新的轻质材料是可能的。本研究制备了两层材料（Al/Mg 合金）和三层材料（Al/Mg/Al 合金）。采用铝含量较高(铝的重量比为9％至12％)的高强度镁合金作为包层的芯材。已经表明，含12%铝的AZ121的拉伸应力为420MPa，0.2%屈服强度为380MPa。对熔覆界面的分析结果显示，界面处存在由15微米的金属间化合物组成的混合层。此外，通过 EDSD 分析还检测到金属间化合物 Al3Mg2 和 Mg17Al12。进行 90 度弯曲测试以检查不同材料的连接。 90度弯曲测试结果表明，该界面可以成功熔覆。
