Research Abstract |
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.
