简要介绍了侧向挤压的原理、特点及其与正挤压、反挤压比较的优缺点。通过对镁钢复合棒的侧向挤压实验，了解侧向挤压的金属变形过程，并进行了变形区与镁钢复合棒成品的金相组织观察，以及成品显微硬度测量。结果证明了侧向挤压的优点，即可以进行大直径芯线的包覆，避免了正挤压时芯材必须弯曲的缺点。对侧向挤压制品的金相观察和显微硬度检测证明焊合区性能良好，与基体无甚差别，取得了良好结果。

The theory and characters of side extrusion were introduced, the differences between side extrusion and direct extrusion, reverse extrusion were discussed. Through the side extrusion experiment of magnesium-clad-steel, the metal forming process of side extrusion was studied.The microstructure of metal extrusion deforming region and product was studied,the micrographic hardness of product was also studied.
