Plastic deformation of bunsenite (NiO) at temperatures below 1 050 °C

摘要: Constant strain rate compression tests along and have been performed on NiO single crystals (e˚∼7×10 −5 s −1 ). Yield stresses, work hardening rates thermal activation parameters measured between 77 K et 1323 K. The flow-stress for samples compressed shows an anomaly at the Neel temperature much smaller than one previously published [3, 5]. plastic anisotropy is compared to other ionic compounds mechanism are discussed based mechanical data Essais de a vitesse constante ) sur des monocristaux selon .
