Abstract:The effects of solution temperature on the microstructure, electrical conductivity, mechanical properties and bending properties of C70250 alloy were investigated by optical microscope (OM), scanning electron microscope (SEM), electrical conductivity measuring instrument, mechanical property test and bending test. The results show that when the solution temperature is adjusted from 720℃ to 900℃, the strength is improved, the electrical conductivity is reduced, the precipitates are more uniform and the bending performance is better under the same cold deformation and aging treatment processes.
