Effect of Annealing Temperature on Microstructure and Properties of Cu-Fe-P Alloy
In this paper,the microstructure of C19210(Cu-0.1Fe-0.03P)alloy annealed at different temperatures is observed,and its tensile strength,microhardness and electrical conductivity are measured.The result show that the recovery and recrystallization of rolled C19210 alloy occur in sequence at 200～500 ℃.The tensile strength of C19210 alloy decreases when the annealing temperature increases,but the tensile strength increases slightly to 416MPa at 450℃ under the combined effects of work hardening weakening,dispersion strengthening and grain size evolution.The elongation and conductivity of C19210 alloy increase with the increase of annealing temperature,and the microhardness decreases.However,due to the second phase precipitation,the hardness increases to 128HV at 400℃ and then decreases rapidly.
