摘要
采用自行研制的高温同轴双简流变仪对半固态ZA12合金的流变性能进行研究，结果表明，半固态合金的剪切应力与剪切时间的关系曲线的特征与固相分数和剪切速率有关。此外，在稳态条件和瞬态条件下。
The rheological behavior of semi-solid ZA12 alloy was studied using a specially designedhigh temperature Coutte rheometer. The r sults show that the characteristic of the relationship curvesbetween shear stress of the semi-solid ZA12 alloyoand shear time is related to the solid fraction and shearrate. In addition, the semi-solid alloy slurry exhibits the differeflt rheological behaviors under the conditionsof steady state and transient state.
