本文以液态模锻和液态挤压研究为基础，提出了一种新型的颗粒增强金属基复合材料的制造方法，并采用实验观察和理论分析手段，对搅融混合后的半固态浆料的挤压过程进行研究，揭示了复合体在流动中凝固、凝固中塑性变形的力学特征，为正确选择工艺参数和过程的稳定奠定基础。 Based on the research of liquid die forging and liquid extrusion, a new method for manufacturing particle reinforced metal matrix composites was proposed. The experimental observation and theoretical analysis were used to analyze the squeezing and mixing of semi-solid slurry Pressure process to reveal the mechanical characteristics of the composite in the flow of solidification, plastic deformation during solidification, the correct choice of process parameters and the process of laying the foundation.
