Abstract Scope |
Grain refinement of Mg alloys has been major research topic over the past decades, because it has been considered as one of the effective approaches to increase the strength and ductility, simultaneously. Among the various methods, superheating method is an effective grain refinement method of Mg-Al alloys. This process involves heating the melt to about 150℃~260℃ above the liquidus temperature, followed by a rapid cooling to the pouring temperature. With the simple control of the melt, a successful grain refinement can be achieved for grain refinement of Mg-Al alloys. However, a clear mechanism has not yet been identified yet. In this study, literatures of recent grain refinement studies were studied in detail, and experiments were performed to clarify the grain refining mechanisms of Mg–Al alloys by superheating. Grain size of Mg-Al alloys were analysed before and after superheating and intermetallic particles were thoroughly investigated using vacuum filtering technology. |
