Solid State Amorphization of Ti₆₀Si₄₀ Alloy via Mechanical Alloying

Abstract:

The effect of milling time on the microstructure evolution and formation of amorphous phase of Ti₆₀Si₄₀ alloy produced by mechanical alloying (MA) has been investigated. Laser diffraction, Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and Differential Scanning Calorimetry (DSC) were employed to characterize the particle size, morphology and structure of mechanically alloyed Ti₆₀Si₄₀. When the milling time is increased to 20 h, the particle size decreases from 23.7 to 4.7 μm, the shape of the particles changes to spherical and the crystalline structure is transformed into an amorphous phase. The amorphous Ti₆₀Si₄₀ alloy is stable when heating up to 750oC. Above this temperature, the cold crystallization of the intermetallic compounds Ti₅Si₃ and/or Ti₅Si₄ begins.
