摘要：

The　influence　of　the　current　density　and　frequency　on　the　mechanical　behavior　of　the　W-CeO2　rod　was　studied　during　tension　tests　in　which　electric　current　was　applied　to　the　deformation　workpiece.　A　larger　decrease　in　material　flow　stress　and　great　improvement　in　the　formability　were　observed　in　electrically　assisted　tests　compared　to　the　normal　tests.　The　scanning　electron　microscopy　observation　showed　that　the　fracture　mechanism　of　tungsten　material　changed　from　brittle　fracture　to　ductile　fracture,　and　the　second　phase　fractured,　which　even　became　spheroidizing　shape.　©　(2015)　Trans　Tech　Publications,　Switzerland.
