Study on Modeling Technique and Internal Quality Control for Heavy Forgings

It is an effective method of studying the theory of forging control for heavy forgings by using the modeling technique. The physical and numerical modeling technique, such as high temperature moiré method, was developed for its outstanding advantages in reducing experimental period. Because the severe quality problems existed in the production of heavy forgings, the forming process of internal faults in heavy forgings and relative factors were studied. The phenomena of shear band in the deformation, microcracks congregated around inclusions, damage and recovery of faults were discovered and their principles were investigated further. It plays an important role that the standard was established in improving the product quality.
