Owing to the brittle nature of high-temperature superconductors, their electromechanical properties need to be studied and understood prior to magnet design and construction. The irreversible degradation of the critical current at high strains has been previously correlated to damage in the microstructure of the superconductor. The origin of the much smaller reversible strain dependence of the superconducting properties of Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub> O<sub>8+x</sub> wires has not yet been studied in detail. In this paper, we determine the cause of the reversible effect of strain on the pinning force and the critical current at temperatures ranging from 4 K to 65 K. Measurements were made as a function of tensile strain in magnetic fields up to 16 T. The irreversibility fields, determined from the macroscopic pinning force at various temperatures and strains, and the critical temperature of the Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+x</sub> wire were found to be strain dependent. The reversible change in critical current and pinning force in Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+x</sub> superconducting wires can be solely attributed to the dependence of the critical temperature on pressure.</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Keywords : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>bismuth compounds; calcium compounds; critical currents; high-temperature superconductors; strontium compounds; superconducting transition temperature; tensile strength; wires; Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8</sub>; critical current; critical temperature; high temperature superconductor; magnet design; microstructure; pinning force; pressure dependence; reversible strain effect; superconducting wires; temperature 4 K to 65 K; tensile strain; Force; Integrated circuits; Strain; Superconducting magnets; Temperature dependence; Temperature measurement; Wires; Axial strain; Bi-2212 wire; critical current; flux pinning; irreversibility field;</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>fLanguage : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>English</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Journal_Title : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>Applied Superconductivity, IEEE Transactions on</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Publisher : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>ieee</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>ISSN : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>1051-8223</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Type : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>jour</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>DOI : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>10.1109/TASC.2011.2174630</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Filename : </div><div class='valueDiv leftDirection leftAlign col-xs-8 col-sm-10 fullRecValueEnglish'>6107560</div> </div> <div class='row'> <div class='leftDiv labelDiv col-xs-4 col-sm-2 fullRecLabelEnglish'>Link To Document : </div><div class='valueDiv leftDirection leftAlign fullRecValueEnglish col-xs-8 col-sm-10'><a href='https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1401843' target='_blank'>https://search.ricest.ac.ir/dl/search/defaultta.aspx?DTC=49&DC=1401843</a></div> </div> </div> <div class='leftDiv labelDiv leftAlign backLinkEnglish'><a href='javascript:history.back()'><img src='../CSS/Back.png' class='backImage' alt=
