文摘
- •
Mg and Ti were joined successfully by laser welding-brazing with AZ91 filler.
- •
Effect of Al content from filler on interfacial reaction was comparatively studied.
- •
More Al atoms diffused into the interface with AZ91 filler.
- •
Newly formed reaction layer was identified at the AZ91/Ti interface.
- •
Reaction layer prevented crack propagation and improved joint strength.
