摘要

利用自行研制的机械振动装置成功制备了ZL101铝合金半固态浆料。研究了保温温度、浇注温度这两个参数对浆料质量的影响。研究表明

保温温度越低

固相率越高;保温温度升高

半固态浆料的显微组织较为圆整

但是晶粒的平均直径有所增大。浇注温度较低

制备的ZL101半固态浆料中的初生α-Al晶粒较圆整

尺寸细小

最终固相率也相对较高。合适的保温温度为595～605℃左右

浇注温度为635～660℃左右。

Abstract

We have developed a mechanical vibration to successfully prepare the ZL101 aluminum alloy semi-solid slurry. The effects of holding temperature

pouring temperature on the slurry quality have been described. The results indicate that with the decrease of holding temperature

the solid fraction is increased; with increasing holding temperature

the microstructure in the semi-solid slurry can become more and more spheroidal with average size of grain slightly increasing. With decreasing pouring temperature

primary α-Al phase in the semi-solid slurry can be refined and spheroidized

resulting in the higher solid fraction in the slurry. The optimized processing parameters can be obtained including holding temperature at about 590～605℃ and pouring temperature at about 635～660 ℃.
