Abstract

This study examined the glass formation range of Ti _94-x-yCu _xNi _ySi ₄B ₂ alloy powders synthesized by mechanical alloying technique. According to the results, after 5-7 h of milling, the mechanically alloyed powders were amorphous at compositions with (x+y) equal to 20-40%. For the compositions with (x+y) larger than 45% or smaller than 10%, the structure of ball-milled powders is a partial amorphous single phase or coexistent partial amorphous and crystalline phases, respectively. The thermal stability of the amorphous powders was also investigated by differential thermal analysis. As the results demonstrated, several amorphous powders were found to exhibit a wide supercooled liquid region before crystallization. The temperature interval of the supercooled liquid region defined by the difference between T _g and T _x, i.e. ΔT(=T _x-T _g), are 52 K for Ti ₇₄Ni ₂₀Si ₄B ₂, 74 K for Ti ₆₄Ni ₃₀Si ₄B ₂, 58 K for Ti ₆₄Cu ₂₀Ni ₁₀Si ₄B ₂, and 61 K for Ti ₇₄Cu ₁₀Ni ₁₀Si ₄B ₂.
