摘要：为探讨不同掺杂元素对黄铜合金切削性能的影响,制备了5种掺杂不同元素的黄铜(2%(质量分数,下同)Sn黄铜、0.5%Sn黄铜、Sn-Fe黄铜、Pb黄铜、Si黄铜),并与H59黄铜的组织金相、力学性能、切削性能等进行对比。结果表明,2%Sn黄铜切削性能优于0.5%Sn黄铜;Sn-Fe黄铜和Pb黄铜因其晶界弥散着第二相颗粒质点,使得其切削和断屑性能较好;6种黄铜的切削力大小顺序为:0.5%Sn黄铜>2%Sn黄铜>Sn-Fe黄铜>Si黄铜>H59黄铜>Pb黄铜;Pb黄铜的切削性能较好但机械强度较差,Si黄铜具有不错的机械强度和切削性能。
In order to investigate the influence of different doping elements on the machinability of brass alloys,five types of doped brass alloys were prepared:2%Sn brass,0.5%Sn brass,Sn-Fe brass,Pb brass,and Si brass.Their microstructure,mechanical properties,and machinability were compared with H59 brass.The results indicate that the cutting performance of tin-brass with 2%(mass fraction)Sn is superior to that of Sn brass with 0.5%(mass fraction)Sn.Sn-Fe and Pb-brasses exhibit excellent cutting abilities and chip-breaking properties due to the presence of second phase particles dispersed along their grain boundaries.The ranking order for cutting forces among these six types of brasses is as follows:0.5%Sn brass>2%Sn brass>Sn-Fe brass>Si brass>H59 brass>Pb brass;while Pb-brass demonstrates good machinability but poor mechanical strength,Si-brass exhibits both good machinability and improved mechanical strength.
