High strength bulk aluminum has been prepared by mechanical milling and press-forming processes.The bulk aluminum exhibits a high tensile strength of 537 MPa and a yield strength of 495 MPa.Characterization of microstructures reveals that the grain size of the bulk aluminum is between 0.5~5 μm.The high strength of pure aluminum is benefit from the fine grain size.The low fabrication cost with mechanical milling and press-forming is suitable for industrialized production.
- bulk ultrafine aluminum,
- mechanical milling,
- rapid solidification,
- grain refinement
