前文将各种锻造法的解析结果进行了比较,说明了对于钢锭内部的锻造效果具有各自的特征。总之,平均应力及有效应变对锻造效果有一定的作用。对于内部空隙的锻合问题,采用单向压缩应力或二向、三向压缩应力,以达到锻合所需的压下率是不同的,同时,加大有效应变也有一定的效果。为了得到实际锻造时应力应变对锻件内部空隙的影响,可用简单的模拟试件来考察空隙的变
The foregoing analysis of the results of various forging methods were compared, indicating that forging effect within the ingot has its own characteristics. In short, the average stress and effective strain on the forging effect has a certain effect. For the in-space forging problems, the use of unidirectional compressive stress or two-way, three-direction compressive stress, to achieve the required forging reduction rate is different, while increasing the effective strain also have some effect. In order to obtain the actual forging stress and strain on the forgings of the internal voids, can be a simple simulation of specimens to examine the voids
