摘要

Nanocrystalline Ti and Ti-20 at.% Mg produced by mechanical milling were characterized using nanobeam diffraction. Metastable to (hexagonal) and y (orthorhombic) phases were observed in the pure Ti, while y, a new orthorhombic e phase and a face-centred cubic (fcc) phase were identified in the Ti-Mg.γ, found so far only at high pressures, was produced by a combination of high impact pressure and shear stress during milling. The forced dissolution of Mg caused the formation of the s and fcc phases.
