Nanograined (NG)/ultrafine‐grained (UFG)structures show enhanced cellular response of pre‐osteoblasts. Cell proliferation, viability, and morphology on phase‐reversion annealed NG/UFG austenitic stainless steel were observed to be favorably modulated in comparison to conventional coarse‐grained austenitic stainless steel. The improvement in cellular response is ascribed to NG/UFG structure and hydrophilicity of the cell substrate.
