Strength, plasticity and thermal stability that are highly desired for structural materials could be realized through optimizing microstructure and/or composition of materials. Crystalline materials are strengthened naturally through impeding the motion of dislocations which are generally achieved through manipulation of crystal imperfections. Tailoring the structural characters and properties of grain boundaries or reinforced units has been demonstrated to have positive effects on achieving the synergic combination of strength and plasticity. We synthesized NC Ni with the high crystallization temperature amorphous ceramic SiOC at the grain boundaries or embedded in Ni grains through magnetron co-sputtering techniques and following thermal treatments. Microstructure evolution and mechanical properties with thermal treatment, deformation temperature and strain rate have been systematically studied.
