Abstract
This study aims to produce magnesium alloy strip with boss and rib directly from molten metal. Magnesium alloy is the lightest structural material, so it is expected to widely use for small electronic device and etc. We studied about melt drag process. Melt drag process is one of single roll strip casting process. We use model melt drag experimental device to produce rapid solidified magnesium strip with boss and rib. Substrate is used on model experimental device instead of roll to easily research shape of substrate. Diameter of boss is 5 mm, 7.5 mm and 10 mm. Height of boss is 6 mm. We revealed on this study that the experimental conditions to get good shape boss and rib, improvement substrate shape for good boss and rib, microstructure and etc.

Summary
Magnesium alloy is the lightest structural material, so it is expected to widely use for small electronic device and etc. We studied about melt drag process [1]. Melt drag process is one of single roll strip casting process. We use model melt drag experimental device to produce rapid solidified magnesium strip with boss and rib. Model experimental device [2] has been designed for researching contacting conditions between molten metal and substrate of solidification roll. Forming processes of boss and lib are such as press forging [3], die-casting and welding. Press forging needs big press machine for big load, die-casting limits kind of alloy, welding is difficult for magnesium. This study aims to produce magnesium alloy strip with boss and rib directly from molten metal. Boss and rib shapes were machined on substrate of model melt drag device.
