Recovery of mechanical strength by surface crack disappearance via thermal oxidation for nano-Ni/Al2O3 hybrid materials

Recovery of mechanical strength as a function of heat-treatment temperature and time was investigated in α-Al2O3-based hybrid materials containing with 5vol% dispersed Ni nanoparticles (nano-Ni/Al2O3) via fraction of surface crack disappearance. Surface cracks introduced by Vickers indentation disap...
