The　multiaxial　cyclic　characteristic　of　the　thin　tubular　specimen　of　superalloy　GH4169　was　investigated　by　the　strain　control　under　tensional-torsional　loading　at　high　temperature.　The　uniaxial　and　multiaxial　loading　paths　were　adopted　in　fatigue　test.　The　multiaxial　fatigue　behavior　was　studied　by　the　relationship　between　the　cyclic　stress　response　of　tension/torsion　and　the　number　of　cycles　from　recorded　experimental　data.　The　results　showed　that　the　fatigue　life　and　the　characteristics　of　cyclic　hardening　or　softening　not　only　depend　on　the　strain　loading　paths,　but　also　on　the　sequence　of　loading　paths　and　the　loading　parameters.
