Strain-controlled low-cycle fatigue up to 6% was monitored by in situ electrical resistivity measurements. The experimental results show that a great motion of martensite fronts results in a significant accumulation of defects, as evidenced by transmission electron microscopy (TEM), before and after the tensile cycles. This gives rise to an overall increase of the resistivity values up to the maximum deformation. Therefore, the research suggests that shape memory alloy wire has great potential as a stress sensor inside bulk materials.<\/jats:p>","DOI":"10.3390\/ma14164455","type":"journal-article","created":{"date-parts":[[2021,8,9]],"date-time":"2021-08-09T05:17:06Z","timestamp":1628486226000},"page":"4455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Experimental Analysis of NiTi Alloy during Strain-Controlled Low-Cycle Fatigue"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8307-2303","authenticated-orcid":false,"given":"Pedro Cunha","family":"Lima","sequence":"first","affiliation":[{"name":"University of Coimbra, CEMMPRE, Department of Mechanical Engineering, 3030-790 Coimbra, Portugal"},{"name":"Instituto Federal de Educa\u00e7\u00e3o, Ci\u00eancia e Tecnologia da Bahia\u2014IFBA, Salvador 40301-015, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7616-6793","authenticated-orcid":false,"given":"Patr\u00edcia Freitas","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"University of Coimbra, CEMMPRE, Department of Mechanical Engineering, 3030-790 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8486-5436","authenticated-orcid":false,"given":"Ana Sofia","family":"Ramos","sequence":"additional","affiliation":[{"name":"University of Coimbra, CEMMPRE, Department of Mechanical Engineering, 3030-790 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8274-3734","authenticated-orcid":false,"given":"Jos\u00e9 D.
