摘要

•Al3Ti particles were in-situ synthesized for Ti particles reinforced AZ31 alloys by mechanical milling.•The orientation relationship between Al3Ti particles and Mg matrix was (101¯0)Mg // (001)Al3Ti; [1¯21¯3]Mg // [100]Al3Ti.•Al-HCP and TiAl-MT configurations show higher interfacial stability with the lower interface energy.•The mechanical failure is inclined to initiate in the interior of Mg bulk rather than the interface.
