METHOD OF DETERMINING DEGREE OF CLOSURE OF INTERNAL DEFECTS AT METAL FORMING |
| 摘要 |
A method of determining degree of closure of internal defects at metal forming includes deformation of a sample and a comparison of geometric parameters of a defect before and after deformation. The cavity of internal defect is filled with a colored substance and on the basis of displaced volume after deformation the degree of closure of a defect is determined. |
