摘要：

Ti was used as an interlayer to join Mg and Al alloys by fiber laser welding. The formation of Mg-Al intermetallic compounds could be totally suppressed and the interfacial layer was composed of Al3Ti and small amounts of Al18Ti2Mg3. The mechanism of interfacial layer formation was attributed to the thermodynamic behavior of the formation of intermetallic compounds in Al-Mg-Ti ternary system and to precise control of the laser power.
