摘　　要：实验测定分析了液态浸渗后直接挤压过程的冲头载荷与位移关系曲线及它们各自随时间的变化，指出了不同工艺条件下所获得的载荷－位移曲线存在很大差异的原因，揭示了工艺参数对液态浸渗后的挤压过程性质有着决定性作用。Both the load and the displacement of the ram as well as their relationship during extrusion which directly follows liquid infiltration were experimentally measured and analyzed.The reasens which account for the differences of the load-displacement curves obtained under different technical conditions were pointed out.It was revealed that the technical parameters have determinant influence on the nature of the extrusion process which directly follows liquid infiltration.
