摘要

选取AZ91D镁合金

通过摆振超声振动（LAO-UV）制备镁合金半固态浆料

选取一个试样

通过连续切片技术得到一系列连续的金相图片

利用Mimics软件研究半固态镁合金初生相的空间结构、空间排布及尺寸大小等。与二维金相组织相比

三维定量表征能够更加全面和真实的显示材料内部组织的数据信息

并且通过三维结构分析得出在浇注温度为620℃时

经转管摆振和超声的共同作用有利于其初生相向球晶转变。

Abstract

The AZ91D magnesium alloy semi-solid slurry was prepared by pendulum ultrasonic vibration（LAOUV）.A sample was selected and a series of continuous metallographic images were obtained by continuous slicing technique using Mimics software.The spatial structure

spatial arrangement and size of the primary phase in the AZ91D magnesium alloy were observed and analyzed.Compared with that of two-dimensional

three-dimensional quantitative characterization can more comprehensively and truly present the data information of the internal structure of the material

and through three-dimensional structural analysis

it is concluded that with pouring temperature at 620℃

the shimmy of the rotating tube and the ultrasonic wave are beneficial for primary phase spheroidal transformation.
