    • Abstract
  • The AZ61Mg‒18%Ti (mass fraction) composites were prepared by mechanical milling, vacuum hot pressing, and hot extrusion. The microstructure, room-temperature mechanical properties, and the corresponding strengthening mechanism were studied. The results show that, the average grain size of the magnesium matrix is about 180 nm, the Ti particles and the nano-sized Ti3Al phases are dispersive distribution in the magnesium matrix, and the average grain sizes of Ti particles and Ti3Al phases are 265 nm and 10 nm, respectively. The ultrafine-grained AZ61Mg‒18%Ti composites show the excellent room-temperature mechanical properties, the room-temperature yield strength, the compressive strength, and the fracture strain are 606 MPa, 698 MPa, and 12%, respectively.
