研究了zr55cu35al10块体非晶成形合金的非晶形成能力和反晶化行为，阐明了极高的纳米晶化产物密度（>1023m−3）。采用x射线衍射、透射电镜、差示扫描和等温量热等方法研究了玻璃合金的结晶动力学和结构变化。等温反应过程中观察到的顺序相形成和高纳米晶密度与低浓度（<500ppm）残余氧促进成核的影响一致。
The glass-forming ability and devitrification behavior of a Zr55Cu35Al10bulk glass-forming alloy were examined to elucidate the very high nanocrystallization product density (>1023m−3). The crystallization kinetics and structural changes in the glassy alloy were studied using X-ray diffraction, transmission electron microscopy, differential scanning and isothermal calorimetry methods. The observed sequential phase formation during isothermal reaction and the high nanocrystal density are consistent with the influence of residual oxygen even at low levels (<500ppm) to promote nucleation.
