【摘要】 介绍了装甲车天线弹簧材料——GY157特种弹簧钢丝的研制,选择沉淀硬化半奥氏体钢丝作天线弹簧钢丝材料,确定其化学成分及其控制范围,采用真空感应+电渣重熔工艺冶炼,采用CH工艺冷加工强化,可使该弹簧钢丝的机械性能σ_b>1600MPa、硬度达HRC48以上。更多还原

【Abstract】 The paper introduces the trial-manufacture of GY157 special spring wire for armored vehicle’s antenna. The chemical composition range of the spring steel was defined. After smelted by vacuum induction and electro-slag remelting, and enhanced by the CH technique of cold-working, the special spring wire can obtain the excellent mechanical properties(σ_b>1600 MPa,HRC>48).更多还原
