| Abstract: | The microstructure and phase transformation during crystallization of bulk glass alloyZr52.5 Ni14.6 Al10 Cu17/9 Ti5 prepared by melt injection method are investigated by using XRD, SEM andTEM. The experimental results indicate that a small amount of crystalline appears in the glass matrixafter annealing at near glass transition temperature Tg, but the glass is completely crystallized at nearcrystallization temperature Tx (703 - 723 K) for 600 s, the crystallized phases are Zr2Ni0.67O0.33 and asmall amount of ZrAI and Zr2Cu. After annealing at more high temperature (753 - 823 K) the amountsof ZrAI and Zr2Cu increase, and the alloy consists of nano-sized grains. |
