aging and aging after cold deformation on microstructure and properties of the self-developed CuNiCrSiBeZr alloy with Co free and low Be for slot wedge in turbo-generator rotor were investigated.The results show that the alloy exhibits desirable comprehensive properties after solid solution at 960 ℃ for 1.5 hours +30%
3
8% cold deformation + aging treatment at 490 ℃ for 3 hours
where hardness

525 ℃
827 MPa
779 MPa and 16%
respectively
meeting the requirement of slot wedge in turbo-generator rotor.
