文摘
- •
Mg–Al–Ca alloys containing the single Al2Ca second phase has been successfully in-situ synthesized.
- •
As the content of the Al2Ca phase is 4 wt.%, the finest microstructure of as-cast Mg–Al–Ca alloy is observed.
- •
After hot extrusion, nanoscale plate-like Al2Ca particles dynamically precipitate inside grains.
- •
Mg-4Al2Ca alloys shows superior strength and strengthening mechanisms were discussed.
