Exceptional strengthening in low-alloyed Mg-Zn-Ca-Nd alloy by enhanced dislocation-solute segregation coupling in rotary swaging deformation

Room-temperature rotary swaging (RS) is pivotal for strengthening magnesium alloys. Herein, hot-extruded Mg-1Zn-0.2Ca-0.2Nd (wt.%) alloy achieves exceptional strengthening by tailoring dislocation-solution segregation coupling after 5-pass RS (34% total strain, RS-2 alloy). RS-2 alloy forms an optim...
