The　vulnerable　corrosion　resistance　of　Mg　alloys　is　regarded　as　one　of　the　main　disadvantages　restricting　their　application,　while　it　can　be　used　as　an　extraordinary　specialty　in　some　particular　fields,　such　as　petroleum　exploitation　and　medicine.　In　recent　years,　many　Mg　alloys　with　high　corrosion　rate　and　high　strength　have　been　developed　for　fracturing　temporary　plugging　tools　in　the　oil　exploitation.　This　review　briefly　introduces　the　performance　requirements　of　the　degradable　fracturing　tools　classified　into　mechanical　and　corrosion　properties.　Recent　progress　on　corrosion　behavior　of　degradable　Mg-Al,　Mg-Zn,　Mg-RE　alloys　and　Mg　matrix　composites　is　then　summarized　and　discussed.　Finally,　the　factors　influencing　the　degradation　rate　of　Mg　alloys　are　analyzed　and　divided　into　secondary　phase,　texture,　dislocation,　grain　size　and　surface　film.　From　the　summary,　it　can　be　found　that　addition　of　Ni　or　Cu　to　the　degradable　Mg　alloys　is　a　common　and　effective　method　to　enhance　the　degradation　rate　due　to　increasing　the　amount　of　secondary　phases　and　deteriorating　the　corrosion　product　layers.　For　the　as-extruded　degradable　Mg　alloys,　grain　size,　texture　and　dislocation　are　the　key　factors　affecting　the　corrosion　rate　under　different　processing　conditions.　We　expect　this　review　is　helpful　for　those　who　are　working　on　developing　Mg-based　functional　materials　with　superior　degradation　rate.(c)　2022　Chongqing　University.　Publishing　services　provided　by　Elsevier　B.V.　on　behalf　of　KeAi　Communications　Co.　Ltd.This　is　an　open　access　article　under　the　CC　BY-NC-ND　license　(　http://creativecommons.org/licenses/by-nc-nd/4.0/　)　Peer　review　under　responsibility　of　Chongqing　University
