Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and nanostructured materials with large densities of lattice defects. This field, also known as NanoSPD, experienced a significant progress within the past two decades. Beside classic SPD methods such high-pressure torsion, equal-channel angular pressing, accumulative roll-bonding, twist extrusion, multi-directional forging, various continuous techniques were introduced to produce upscaled samples. Moreover, numerous alloys, glasses, semiconductors, ceramics, polymers, their composites processed. The used synthesize new or stabilize metastable phases advanced mechanical functional properties. High strength combined high ductility, low/room-temperature superplasticity, creep resistance, hydrogen storage, photocatalytic production, CO2 conversion, superconductivity, thermoelectric performance, radiation corrosion biocompatibility are some highlighted properties SPD-processed materials. article reviews recent advances NanoSPD field provides brief history regarding its from ancient times modernity.Abbreviations: ARB: Accumulative Roll-Bonding; BCC: Body-Centered Cubic; DAC: Diamond Anvil Cell; EBSD: Electron Backscatter Diffraction; ECAP: Equal-Channel Angular Pressing (Extrusion); FCC: Face-Centered FEM: Finite Element Method; FSP: Friction Stir Processing; HCP: Hexagonal Close-Packed; HPT: High-Pressure Torsion; HPTT: Tube Twisting; MDF: Multi-Directional (-Axial) Forging; NanoSPD: Nanomaterials by Plastic Deformation; SDAC: Shear (Rotational) SEM: Scanning Microscopy; SMAT: Surface Mechanical Attrition Treatment; SPD: TE: Twist Extrusion; TEM: Transmission UFG: Ultrafine Grained
