N2 - Yield point phenomenon often occurs in fine-grained and ultrafine-grained fcc and bcc metals, which causes a sharp increase in yield stress by source hardening but a rapid decrease in ductility due to the limited work hardening capacity. Here we report that an occurrence of yield point phenomenon in a fine-grained Mg-3Gd alloy can increase the yield stress to a level that facilities the activation of type dislocations and their interactions with type dislocations. As a result, not only the yield stress but also the tensile ductility are improved that suggests a new strategy overcoming the conventional strength-ductility trade-off.
