{"cited_by_count":2181471,"description":"This cluster of papers focuses on the synthesis, characterization, and mechanical properties of nanomaterials, particularly nanocrystalline metals, produced through severe plastic deformation techniques. It explores the effects of grain refinement, grain boundary engineering, and size-dependent deformation mechanisms on the strength and ductility of these materials.","display_name":"Microstructure and mechanical properties","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T10204","wikipedia":"https://en.wikipedia.org/wiki/Nanomaterials"},"field_id":"25","id":"T10204","keywords":[{"display_name":"severe plastic deformation","id":"severe-plastic-deformation","score":0.5627,"url":"https://openalex.org/keywords/severe-plastic-deformation"},{"display_name":"crystal plasticity","id":"crystal-plasticity","score":0.4982,"url":"https://openalex.org/keywords/crystal-plasticity"},{"display_name":"equal channel angular pressing","id":"equal-channel-angular-pressing","score":0.6404,"url":"https://openalex.org/keywords/equal-channel-angular-pressing"},{"display_name":"dislocation dynamics","id":"dislocation-dynamics","score":0.4895,"url":"https://openalex.org/keywords/dislocation-dynamics"},{"display_name":"grain boundary sliding","id":"grain-boundary-sliding","score":0.3297,"url":"https://openalex.org/keywords/grain-boundary-sliding"},{"display_name":"dislocation motion","id":"dislocation-motion","score":0.3038,"url":"https://openalex.org/keywords/dislocation-motion"},{"display_name":"dislocation slip","id":"dislocation-glide","score":0.2826,"url":"https://openalex.org/keywords/dislocation-glide"},{"display_name":"polycrystalline materials","id":"polycrystals","score":0.2406,"url":"https://openalex.org/keywords/polycrystals"},{"display_name":"deformation twinning","id":"deformation-twinning","score":0.2945,"url":"https://openalex.org/keywords/deformation-twinning"},{"display_name":"face-centered cubic metals","id":"face-centered-cubic-metals","score":0.3996,"url":"https://openalex.org/keywords/face-centered-cubic-metals"},{"display_name":"high-pressure torsion","id":"high-pressure-torsion","score":0.5341,"url":"https://openalex.org/keywords/high-pressure-torsion"},{"display_name":"grain boundary migration","id":"grain-boundary-migration","score":0.2977,"url":"https://openalex.org/keywords/grain-boundary-migration"},{"display_name":"texture evolution","id":"texture-evolution","score":0.2355,"url":"https://openalex.org/keywords/texture-evolution"},{"display_name":"screw dislocations","id":"screw-dislocations","score":0.2508,"url":"https://openalex.org/keywords/screw-dislocations"},{"display_name":"high-angle grain boundaries","id":"high-angle-grain-boundaries","score":0.2803,"url":"https://openalex.org/keywords/high-angle-grain-boundaries"},{"display_name":"dislocation nucleation","id":"dislocation-nucleation","score":0.3969,"url":"https://openalex.org/keywords/dislocation-nucleation"},{"display_name":"slip systems","id":"slip-systems","score":0.3422,"url":"https://openalex.org/keywords/slip-systems"},{"display_name":"dislocation structure","id":"dislocation-structure","score":0.2734,"url":"https://openalex.org/keywords/dislocation-structure"},{"display_name":"tensile deformation","id":"tensile-deformation","score":0.2025,"url":"https://openalex.org/keywords/tensile-deformation"},{"display_name":"stacking fault energy","id":"stacking-fault-energy","score":0.2468,"url":"https://openalex.org/keywords/stacking-fault-energy"},{"display_name":"Hall-Petch relation","id":"hall-petch-relationship","score":0.3377,"url":"https://openalex.org/keywords/hall-petch-relationship"},{"display_name":"edge dislocations","id":"edge-dislocations","score":0.2355,"url":"https://openalex.org/keywords/edge-dislocations"},{"display_name":"body-centered cubic metals","id":"bcc-metals","score":0.3537,"url":"https://openalex.org/keywords/bcc-metals"},{"display_name":"nanocrystalline materials","id":"nanocrystalline-materials","score":0.2014,"url":"https://openalex.org/keywords/nanocrystalline-materials"},{"display_name":"low-angle grain boundaries","id":"low-angle-grain-boundaries","score":0.2146,"url":"https://openalex.org/keywords/low-angle-grain-boundaries"}],"legacy_keywords":["Nanocrystalline Materials","Severe Plastic Deformation","Grain Refinement","Strength and Ductility","Metal Processing","Crystal Plasticity","Grain Boundary Engineering","Atomistic Simulation","Size Effects","Deformation Mechanisms"],"openalex_id":"https://openalex.org/T10204","source_created_date":"2024-01-23T15:27:05","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2505","url":"/topics/T10204","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10204","works_count":110098,"label":"Microstructure and mechanical properties","provider":"openalex","revision":"7c98b4f260cae40b","taxonomy_revision":"f050b5d4780b1289","title":"Microstructure and mechanical properties","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36108566574852119","address_version":"morton4x16-v1","coordinates":[3,25,2505,10204],"answer_status":"Directory metadata;
