Abstract
Mechanical milling of pre-alloyed Ti-47.5AI-3Cr (at.%) powder has been carried out in a vibratory mill. The microstructural evolution of the materials was studied as a function of milling time. An ultrafine microstructure was produced with a crystallite size of about 15 nm and a partial amorphization was obtained after 2 hours of milling.
