液态挤压和液态模锻一样,存在着物理化学和力学成形两过程。本文作者在液态模锻理论研究成果基础上,揭示了液态挤压过程的力学特征,包括在挤压力作用下,液态金属在流动中凝固和塑性变形的流动特征;挤压力随行程变化所反映的金属成形的力学特征,从而为过程的确立和应用提供理论依据。

Liquid extrusion, Like Liquid forging, is Characterized by the combination of the two processes of solidifying and mechanical forming. On the basis of the research achievements in liquid forging, the authors, in the paper, have thoroughly analysed the mechanical characteristics of the liquid extrusion process, including the characteristics of the solidifying of the flowing molten metal, the behavior of the plastic flow of the solidified matal, and the metal forming mechanics reflected by the ralationship between the extrusion pressure and the stroke of the punch. These analyses lay a theoretic foundation for the establishment and application of the liquid extrusion process.
