Abstract
The influence of ball milling in a high energy planetary mill on the phase formation in Al50Ti50-xFex (x = 10, 20, 30, 40 at.%) powder mixtures was st udied by X-ray diffraction (XRD) and differential scanning calorimetry (DSC ). Mechanical alloying (MA) leads to the formation of single phase nanocrys talline alloys. Their structures depend on the initial composition of powde r mixtures: hcp(C14), x = 10; fcc(D8a), x = 20, 30; bcc(B2), x = 40. The MA alloys preserve their nanocrystalline state in the course of heating up to 500 degrees C. (C) 1998 Elsevier Science S.A. All rights reserved.
