The rotary swaging process and subsequent ageing improved the yield stress in tension and compression. In the present study, the investigation was focused on fatigue behaviour. The samples were cycled in a symmetric regime with a frequency of 35 Hz. A dependence of the stress amplitude on the number of cycles up to the fracture was estimated. The microstructure of the samples and fracture surfaces was analysed with a scanning electron microscope. The fatigue process was influenced by the pronounced texture formed in the swaging process. The fatigue properties of the swaged samples improved substantially\u2014the endurance limit based on 107 cycles was approximately 120 MPa\u2014compared to those of the cast alloy. The analysis of the fracture surfaces showed a transcrystalline fatigue fracture.<\/jats:p>","DOI":"10.3390\/ma15217541","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T22:36:17Z","timestamp":1666910177000},"page":"7541","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Fatigue in an AZ31 Alloy Subjected to Rotary Swaging"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3651-9587","authenticated-orcid":false,"given":"Zuzanka","family":"Trojanov\u00e1","sequence":"first","affiliation":[{"name":"Faculty of Mathematics and Physics, Charles University, Ke Karlovu 3, 121 16 Praha, Czech Republic"},{"name":"Comtes FHT, Pr\u016fmyslov\u00e1 996, 334 41 Dob\u0159any, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4405-9947","authenticated-orcid":false,"given":"Zden\u011bk","family":"Drozd","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Physics, Charles University, Ke Karlovu 3, 121 16 Praha, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5029-6901","authenticated-orcid":false,"given":"Krist\u00fdna","family":"Halme\u0161ov\u00e1","sequence":"additional","affiliation":[{"name":"Comtes FHT, Pr\u016fmyslov\u00e1 996, 334 41 Dob\u0159any, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e1n","family":"D\u017eugan","sequence":"additional","affiliation":[{"name":"Comtes FHT, Pr\u016fmyslov\u00e1 996, 334 41 Dob\u0159any, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tereza","family":"Hofrichterov\u00e1","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Physics, Charles University, Ke Karlovu 3, 121 16 Praha, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Pal\u010dek","sequence":"additional","affiliation":[{"name":"Department of Materials and Engineering, University of \u017dilina, Univerzitn\u00e1 1, 010 26 \u017dilina, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7034-5547","authenticated-orcid":false,"given":"Peter","family":"Min\u00e1rik","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Physics, Charles University, Ke Karlovu 3, 121 16 Praha, Czech Republic"},{"name":"Research Centre, University of \u017dilina, Univerzitn\u00e1 8215\/1, 010 26 \u017dilina, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom\u00e1\u0161","family":"\u0160kraban","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics and Physics, Charles University, Ke Karlovu 3, 121 16 Praha, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7527-5020","authenticated-orcid":false,"given":"Franti\u0161ek","family":"Nov\u00fd","sequence":"additional","affiliation":[{"name":"Department of Materials and Engineering, University of \u017dilina, Univerzitn\u00e1 1, 010 26 \u017dilina, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"782","DOI":"10.1016\/j.actamat.2012.10.038","article-title":"Extreme grain refinement by severe plastic deformation: A wealth of challenging science","volume":"61","author":"Estrin","year":"2013","journal-title":"Acta Mater."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"881","DOI":"10.1016\/j.pmatsci.2006.02.003","article-title":"Principles of equal-channel angular pressing as a processing tool for grain refinement","volume":"51","author":"Valiev","year":"2006","journal-title":"Prog.
