本文用常温云纹法与数值模拟法研究了筒体锻件整体镦粗与局部镦粗工艺的变形规律，得到了整体镦粗工艺的坯料尺寸图。
The deformation law of both solid and local upsetting processes for cylinder forging is investigated by moire method at room temperature and numerical simulation in this paper.
研究发现，锻压过程中合金的流动性整体较好，在锻件头部和杆部边缘处充填性稍差，主要的缺陷也易在这些部位产生。
It is found that the alloy has a better mobility in forging process. Lack of filling occurred in the head and the edges. The main flaw is also easy to produce in these parts.
水平V形砧锻造法在内部应力状态、金属纤维组织、锻件的整体性能、宏观几何形状等方面都优于普通平砧锻造法。
