摘要	In this work, the plastic deformation of micro/nanoscale AlON ceramic pillars with different crystallographic orientations was investigated by in situ compression on scanning electron microscopy (SEM) system. The experimental results demonstrated a 'smaller is stronger' size dependence of the yield strength of -, - and -oriented AlON micro/nanopillars with scaling exponents of −0.19, −0.24 and −0.33, respectively. Transmission electron microscopy (TEM) illustrated that the Lomer-Cottrell dislocation reaction dominated the plastic deformation of -oriented pillars. The plastic deformation of -oriented AlON pillars was driven by rotation of the slip region, whereas the stress of -oriented pillars were released through microcracks and plastic deformation. © 2024 Elsevier Ltd
