Influence of Heat Treatment Processing on Properties of CuNiMnFe Alloy

Shang Zaiyan*,Wang Xinping,Yang Yonggang,Yang Yazhuo(Grikin Advanced Materials Co.Ltd.,General Research Institute for Non-Ferrous Metals,Beijing 102200,China)  
CuNiMnFe alloy was prepared by vacuum induction melting.The microstructure of alloy before and after uniform heat treatment was analyzed.The effect of quenching and aging processing on the properties of the alloy was researched as well.The results showed that the component of the alloy was uniform distributed after uniform heat treatment at 800 ℃ for 4 h.The alloy was strengthened after hot-forging and aging heat treatment.When aged at 440 ℃ for 44 h,the tensile strength and hardness could reach 1240 MPa and 370HV at room temperature,the tensile strength could reach 990 MPa at 400 ℃.
