The weld quality, in terms of the microstructure and mechanical properties, was investigated after stress relief annealing (SRA) at 750 \u00b0C for 2 h and compared with the as-welded (AWed) results. The central weld zone (CWZ) microstructure in the AWed condition consisted of recrystallized prior-\u03b2 grains with \u03b1\u2019 martensite, which transformed into an acicular \u03b1+\u03b2 structure after SRA. The hardness in the AWed condition was highest in the CWZ and decreased sharply through the thermomechanically affected zones (TMAZ) to the parent materials (PMs). After SRA, the hardness of the CWZ decreased, mainly due to tempering of the \u03b1\u2019 martensite microstructure. Static tensile testing of the dissimilar welds in both the AWed and stress relief annealed (SRAed) conditions resulted in ductile fracture occurring exclusively in the Ti-6Al-4V side of the joint. The promising results on joining of Ti-64 to Ti-6242 provide valuable insight for tailoring performance of next-generation aero-engine products.<\/jats:p>","DOI":"10.3390\/ma13173664","type":"journal-article","created":{"date-parts":[[2020,8,19]],"date-time":"2020-08-19T09:22:31Z","timestamp":1597828951000},"page":"3664","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Joining of Dissimilar Alloys Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo-0.1Si Using Linear Friction Welding"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9066-2419","authenticated-orcid":false,"given":"Sidharth","family":"Rajan","sequence":"first","affiliation":[{"name":"Mechanical and Aerospace Department, Carleton University, Ottawa, ON K1S 5B6, Canada"},{"name":"National Research Council Canada, Aerospace Research Center, Aerospace Manufacturing Technologies Center, 2107 chemin de la Polytechnique, Montr\u00e9al, QC H3T 1J4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7662-984X","authenticated-orcid":false,"given":"Priti","family":"Wanjara","sequence":"additional","affiliation":[{"name":"National Research Council Canada, Aerospace Research Center, Aerospace Manufacturing Technologies Center, 2107 chemin de la Polytechnique, Montr\u00e9al, QC H3T 1J4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javad","family":"Gholipour","sequence":"additional","affiliation":[{"name":"National Research Council Canada, Aerospace Research Center, Aerospace Manufacturing Technologies Center, 2107 chemin de la Polytechnique, Montr\u00e9al, QC H3T 1J4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abu Syed","family":"Kabir","sequence":"additional","affiliation":[{"name":"Mechanical and Aerospace Department, Carleton University, Ottawa, ON K1S 5B6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,19]]},"reference":[{"key":"ref_1","first-page":"1353","article-title":"A Review on BLISK Technology","volume":"2\u20135","author":"Kumar","year":"2013","journal-title":"Int.
