Learning on ScreenTensile Stress in Cast Iron: Changes in the Micro-Structure
- Synopsis
- Shows the changes on polished and on polished and etched surfaces of globular grey cast iron (GGG-50) under tensile stress. A specially developed sample, with large radius and two opposite notches, is bi-directionally and evenly stretched on a special tensile machine. The worst deformation occurs at the smallest cross-section of the sample, where the changes can also be microscopically observed. The stretch behaviour in the elastic and plastic range until the breaking of the sample is filmed. As a result of the 3-phase construction of GGG-50, the individual components of the structure react very differently to the strain. The break occurs spontaneously after deformation. An Encyclopaedia Cinematographica film.
