Tungsten,　with　excellent　properties,　has　become　one　of　the　candidate　materials　for　plasma　facing　materials　in　nuclear　fusion　reactor.　During　the　operation　of　nuclear　fusion　reactor,　tungsten　will　be　exposed　to　high　thermal　load　irradiation,　high　hydrogen/helium　plasma　irradiation　and　high　energy　neutron　irradiation.　Among　them,　the　transmutation　element　Re　generates　by　neutron　irradiation　of　tungsten,　which　will　continue　to　produce　and　accumulate　in　tungsten　to　form　the　transmutation　product　tungsten-rhenium　alloys.　Therefore,　the　thermodynamic　parameters　and　thermal　loading　resistance　of　tungsten　plasma　facing　materials　have　changed,　which　will　affect　the　service　properties　of　plasma　facing　materials,　and　even　be　related　to　the　stable　operation　of　the　reactor.　At　present,　the　generation　of　fusion　high-energy　neutrons　under　laboratory　conditions　is　limited.　Therefore,　the　research　on　the　transmutation　product　tungsten-rhenium　alloys　mainly　bases　on　the　tungsten-rhenium　alloys　prepared　in　the　laboratory.　In　this　paper,　the　major　preparation　technology　and　thermal　loading　behavior　of　tungsten-rhenium　alloys　at　present　were　summarized,　and　the　existing　scientific　problems　in　the　thermal　loading　behavior　of　tungsten-rhenium　alloys　were　analyzed,　which　provided　reference　for　the　application　of　tungsten　as　plasma　facing　materials　in　future　nuclear　fusion　reactor.
