摘要 半固态合金浆料的本质特性依靠宏观因素.这些因素控制着材料的流变行为,它们又可转化为内变量和外交量.内变量包括因相颗粒的团块化程度、流体粘度、颗粒尺寸、颗粒形貌和颗粒尺寸的分布外变量包括温度和剪切速率.在原来的简单模型上,根据半固态合金浆料的不同特性,得出不同条件下的新模型. The constitutive behavior of semisolid slumes depends on a number of macroscopic factors. These factors translate to internal variables and external variables that govern the rheological behavior of the material. Internal variables include a measure of the degree of agglomeration among solid pericles, fluid phase viscosity, particle size, particle morphology, and distribution of particle sizes. External variables are temperature and shear rate. According to the different characters of semisolid slurries, we can give the corresponding new models under the different conditions on the basis of the primary models.
