Prolonged plastic deformation related to the microindentation of MgO single crystals

摘要

The plastic deformation regions near the indentations on the (001) plane of MgO single crystals were investigated for an indentor under load and after unloading. It was established that the completion of slip-line structures arising during indentor penetration occurred during indentor removal. The presence of prolonged plastic deformation has been explained by considering the impulse character of the microindentation process of MgO at room temperature. [References: 25]
