    Abstract

    The micro-hardness,electric conductivity and tensile strength of Cu-2.32Ni-0.57Si-0.05P alloy with different cold deformations after varied aging treatments have been measured,and the precipitates in the alloy have been observed by TEM and SEM.The results show that the comprehensive properties of the alloy can be greatly improved with cold deformation and aging treatment.The desirable comprehensive properties of the different cold deformed alloy can be observed with aging at 450 ℃ after solid solution at 900 ℃ for one hour.The micro-hardness and electric conductivity of 80% cold deformed alloy can reach 240 HV and 23.78 MS/m,respectively,with aging at 450 ℃ for one hour,while the tensile strength of the 40% cold deformed alloy can reach 568 MPa with aging at 450℃ for one hour.The dispersively distributed δ-Ni2Si phase with fine grain size can be precipitated from the alloy during aging treatment,which is gradually grown with extending aging time.
