| 研究開始時の研究の概要 |
Solid-state precipitation is one of the most effective methods to strengthen various engineering alloys, particularly in 6xxx series aluminum alloys. However, the same approach has not been widely adopted in commercial Mg alloys due to their poor and sluggish age-hardening response. This research aims to develop a new precipitation-hardenable Mg alloy that shows strong and rapid age-hardening response.
|
| 研究成果の概要 |
Age-hardening response of Mg-Ag-Ca, Mg-Li-Al and Mg-In-Gd alloys has been evaluated to clarify whether the mixing enthalpy value and the atomic size of solute elements are important factors to determine the formation of precipitates.

| 研究成果の学術的意義や社会的意義 |
Precipitation has not been widely adopted in commercial magnesium alloys due to their poor and sluggish age-hardening response. This project aims to provide a knowledge platform that can provide us valuable insight into the formation mechanism of the precipitates in magnesium alloys.
