The finishing temperature during hot rolling of beryllium bronze has significant impact on the microstructure and properties of beryllium copper alloy plates.Mechanical properties and microstructure of beryllium copper alloy plates with different hot rolling finishing temperatures subjected to identical subsequent cold rolling and heat treatment processes were analyzed by tensile property,hardness and electrical conductivity measurements,along with SEM and EDS.The corresponding variation trends were investigated.The results indicate that with increasing the hot rolling finishing temperature from 520℃to 620℃,the Vickers hardness,tensile strength,yield strength,elongation after fracture and elastic modulus of beryllium copper alloy plates gradually increase,while the electrical conductivity decreases.This is primarily due to the more severe grain boundary reactions and highβ-phase content in the beryllium copper alloy plates at lower hot rolling finishing temperature,leading to the deterioration of alloy properties.
