Study of development of strain in plane strain compression test

Popis výsledku v původním jazyce

Plane strain compression test (PSCT) is a plastometric method for measuring flow stress with strictly defined thermomechanical parameters. Its advantage over torsion testing is in better conditions for exploring the resulting microstructure by means of metallography or microhardness testing. In essence, the plane strain compression test is particularly suitable for physical simulation, though ideally simplified, of rolling. Its weakness is in that it does not allow exploring formability limits and requires a special Gleeble plastometer. A prism-shaped sample heated to the forming temperature by passing electrical current is compressed between two rectangular dies providing constant strain rate. The dies are pressed against the specimen, the height of which changes, leading to its spreading to the sides. In this experiment, plastometric (PSCT) tests of 38MnVS6 microalloyed steel were carried out in Gleeble 3800 plastometer in the temperature range 850-950°C at strain rates of 0.5, 5 and
