Strain-Induced Ultrahard and Ultrastable Nanolaminated Structure in Nickel X. C. Liu1,*, H. W. Zhang1,*, K. Lu1,2,† + Author Affiliations 1Shenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China. 2Herbert Gleiter Institute of Nanoscience, Nanjing University of Science and Technology, Nanjing 210094, China. ↵†Corresponding author. E-mail: lu@imr.ac.cn ↵* These authors contributed equally to this work. Abstract Editor's Summary Heavy plastic deformation may refine grains of metals and make them very strong. But the strain-induced refinement saturates at large strains, forming three-dimensional ultrafine-grained (3D UFG) structures with random orientations. Further refinement of this microstructure is limited because of the enhanced mobility of grain boundaries. Very-high-rate shear deformation with high strain gradients was applied in the top surface layer of bulk nickel, where a 2D nanometer-scale laminated structure was induced. The strongly textured nanolaminated structure (average lamellar thickness of 20 nanometers) with low-angle boundaries among the lamellae is ultrahard and ultrastable: It exhibits a hardness of 6.4 gigapascal—which is higher than any reported hardness of the UFG nickel—and a coarsening temperature of 40 kelvin above that in UFG nickel |
