摘要

利用X射线衍射分析仪（XRD）、光学显微镜（OM）和扫描电镜（SEM）对施加不同超声振动处理制备的Al-5Ti-1B晶粒细化剂的微观组织进行观察和分析

并使用工业纯铝作为研究对象进行细化试验。结果表明

在Al-5Ti-1B晶粒细化剂制备过程中

施加超声振动处理能显著改善其组织和细化效果。连续超声处理10 min制备的Al-5Ti-1B晶粒细化剂中TiAl3相均为细小的块状

平均尺寸为12.4μm

TiB2颗粒弥散分布在铝基体中

对工业纯铝的细化效果最好

可将纯铝晶粒细化至307μm。

Abstract

The microstructure and grain refining performance of Al-5 Ti-1 Bgrain refiners prepared by different ultrasonic treatment were described by using X-ray diffraction（XRD）

optical microscopy（OM）and scanning electron microscopy（SEM）.Meanwhile

refining effects of pure aluminum was observed with the Al-5 Ti-1 B master alloy.The results show that the ultrasonic vibration applied in fabrication of Al-5 Ti-1 Bgrain refiner can improve greatly the microstructure and grain refinement performance of the grain refiner.With continuous ultrasonic treatments for 10 minutes

the morphology of TiAl3 exhibits small block-like with average size of 12.4μm and the TiB2 particles are distributed dispersedly in the Almatrix.The grain in pure aluminum refined by the Al-5 Ti-1 B master alloy is about 307μm

exhibiting the desirable refining effects.
