提高对缺陷形成机制的基本认识对于进一步优化铸造产品至关重要。铝合金中的大多数铸造缺陷的起源通常是由当铸件处于半固态时发生的凝固、偏析和材料输送过程（称为糊状区）来解释的。描述变形和流动性质的糊状区的流变性质由微观结构发展确定，并且在发生以补偿密度差异（包括凝固收缩）的传输过程的效率中起重要作用。
Increasing the fundamental understanding of the mechanisms of defect formation is essential for further optimization of cast products. The origin of most casting defects in aluminum alloys is usually explained by the solidification, segregation, and material transport processes that occur while the casting is in a semisolid state, referred to as the mushy zone. The rheological properties of the mushy zone, which describes the deformation and flow properties, is determined by the microstructural development and plays an important role in the efficiency of the transport processes occurring to compensate for density differences, including solidification shrinkage.
