The initial microstructure influenced the corrosion performance of studied joints due to the formation of secondary phases and their volume fraction changed the galvanic corrosion response of Mg materials. Nd-La addition enhanced the corrosion resistance of IF-Mg joints, where two times higher corrosion resistance was obtained by IF-AZ31B-0.5Nd-0.1La (1110 mils/year (mpy)) joint than IF-AZ31B (3670 mpy). The cross section locations had different secondary phase (SP) volume fraction, SP-distribution and grain orientations which altered the corrosion behavior of joined materials. After the clinching process, the deformed section of IF-AZ31B-0.5Nd-0.1La and IF-AZ31B showed lower corrosion rate than undeformed sections 1040 and 1110 mpy and 2820 and 3670 mpy, respectively.eninfo:eu-repo/semantics/closedAccessAZ31BcorrosionLamechanical clinchingNdArticle10.1007/s11665-022-07221-52-s2.0-8513615982128006Q2279332WOS:000842595300003Q3
