锻造生产中,正确地选择锻造比和锻造方案(镦粗、多方锻、拔长等)是保证产品质量和提高生产率的重要条件。不同锻造比和锻造方案所反映的变形程度是不同的,锻件的组织性能也不同。由于不均匀变形的影响,锻造比和方案对组织性能的均匀性和方向性影响很 Forging production, the right choice forging ratio and forging programs (upsetting, multi-forging, drawing, etc.) is to ensure product quality and improve productivity an important condition. Different forging ratio and forging programs reflect the degree of deformation is different, forgings of the organizational performance is also different. Due to the effect of uneven deformation, the forging ratio and the program on the uniformity and direction of the organizational performance is very
