Abstract：

An　abnormal　reverse　transition　of　intergranular　corrosion　from　sensitization　to　stabilization　was　observed　in　the　Al-6.4　Mg-0.43Mn-0.37Er-0.17Zr　alloy　at　low　annealing　temperatures　between　220　and　260　degrees　C　for　the　first　time.　The　reverse　stabilized　alloy　annealed　at　240　degrees　C　for　5　h　had　excellent　long-term　corrosion　resistance　in　the　deformed　state.　The　corresponding　transmission　electron　microscopy　analysis　showed　that　Al3Mg2　precipitates　distributed　separately　along　grain　boundary,　at　triple　junctions　and　the　Al6Mn　phase　boundary.　The　combination　of　the　low　temperature　reverse　stabilization　and　retarded　recrystallization　by　addition　of　Er　and　Zr　caused　the　high　Mg　aluminum　alloy　to　exhibit　high　corrosion　resistance　and　strain　hardening.　(C)　2019　Acta　Materialia　Inc.　Published　by　Elsevier　Ltd.　All　rights　reserved.
