Supra-nanostructured dual phase metals: introduction of a new family of metallic materials
The mechanisms of materials formation with different nano-structures by high efficient physical method will firstly be reported by illustrating our latest findings / research progress on the supra-nanostructured materials with multiphase embedded structure. The general concept and processing routes will be first introduced. We will present our recent work on an approach that combines the strengthening benefits of nanocrystallinity with those of amorphous phases (metallic glasses) to produce a dual phase material with domains size smaller than <6nm for both phases. This new family of materials exhibits near-ideal strength at room temperature and without sample size effects. The concept can be extended to many other metallic alloys. The exceptional physical and chemical properties can be anticipated. The potential applications for bio-implants and smart phones will be presented.
