| Research Abstract |
Magnesium alloys have the highest light-weight among practical metals, and highspecific-strength to weight ratios. However, because wrought magnesium alloys have poor formability and corrosion resistance at room temperature, the manufacture of Mg/Al clad sheets with thin aluminum sheets has been investigated : high corrosion resistance and good formability can be achieved for a Mg/Al combination with an optimum manufacturing process. In this study, we fabricated Mg/Al clad sheets by rollbonding at a rolling temperature of 300℃. Consequently, the following results were obtained. Firstly, the magnesium and aluminum sheets could be bonded by rollbonding at 30% reduction. Secondly, by annealing at 300℃ for 1h for each pass of rolling, the formability of magnesium was improved markedly. Finally, the insertion of titanium foil between the magnesium and aluminum sheets prevented the peeling of the surface aluminum sheet in the V bending test.
