英文摘要	New Ti-based bulk metallic glasses (BMGs) of Ti32.8+xZr30.2-xNi5.3Cu9Be22.7 (3 <= vertical bar X vertical bar <= 15, at.%) with large size were prepared. The results reveal that the forming of primary icosahedral quasicrystal phase (I-phase) and the enthalpy of the primary crystallization (Delta H-1) were closely related to the glass forming abilities (GFAs). Thecrystallization product of the metallic glass alloys at primary crystallization state is a metastable I-phase. It is demonstrated that apparent activation energy for crystallization obtained by fitting the Kissinger equation at T-x temperature increases with the increase of Ti concentration, while GFAs deteriorate. The Delta H-1 of metallic glasses declines with the increase of Ti concentration. The Ti32.8+XZr30.2-XNi5.3Cu9Be22.7 possess high similar compressive fracture strength of about 1800 MPa, which is one of the best options as structural materials on account of high specific strength and low cost.
