对一种ＳｉＣ颗粒增强铝合金基复合材料的锻造和挤压成形性能进行了研究，绘制了该材料的锻造成形极限图。研究了塑性成形对该材料微观组织的影响和成形的力能变化规律，结果表明：该材料的塑性变形是通过基体的塑性变形来实现的；在热变形时，ＳｉＣ颗粒能够通过转动来调整方位，形成沿金属流动方向的定向分布；塑性成形有助于细化ＳｉＣ颗粒，促进颗粒的均匀分布；材料在热锻时存在一强化极限，与此强化极限对应的变形程度随锻造温度的降低而增大；材料的成形极限与变形温度和变形速度等条件有关。
The forging and extrusion properties of a kind of SiC particle reinforced aluminum alloy matrix composites were studied and the forging forming limit diagram was drawn. The influence of plastic forming on the microstructure of the material and the force variation of the forming process were studied. The results show that the plastic deformation of the material is achieved through the plastic deformation of the matrix. During thermal deformation, the SiC particles can be rotated , Forming an orientation distribution along the direction of metal flow; plastic forming helps to refine SiC particles and promote uniform distribution of particles; there is an enhancement limit for the material during hot forging, and the degree of deformation corresponding to this strengthening limit decreases with decreasing forging temperature Increase; material forming limit and deformation temperature and deformation speed and other conditions.
