英文摘要	Because of their unique properties, bulk metallic glasses and nanocrystalline materials are attractive candidates for structural and functional applications. Their strength is significantly higher than of conventional crystalline alloys. However, one major drawback is their low ductility and their rapid failure. In order to obtain both high strength and high ductility, heterostructures with different phases and different length scales have been developed. This work reports on Ti-based alloys with an in-situ formed composite microstructure, produced in bulk form in a one-step process. The microstructure consists of dendrites distributed in a nanocrystalline matrix whose volume fraction and morphology depend on the nominal composition of the alloy. Structural and compositional analyses of the different phases will be presented as well as the solidification process that leads to such composites. The microstructure will be correlated with the mechanical properties. We will show that, by tailoring the microstructure, high strength or high ductility or different combinations of both can be reached.
