| 摘 要： | 利用ＸＲＤ，ＳＥＭ和拉伸等实验手段对加硼ＨＡｌ７７－２铝黄铜的组织和力学性能进行了研究，实验结果表明：ＨＡｌ７７－２铝黄铜加硼后，无论含Ａｓ与否，均能使之晶粒细化，强度，硬度明显提高，塑性略有下降，在此基础上确定了ＨＡｌ７７－２铝黄铜的最佳硼含量．

| Abstract: | The microstructure and mechanical properties of boron-modified HAl 77-2brass were investigated by XRD,SEM and tension test.The results show that with the increase of boron added to aluminium brass,the grain size of HAl 77-2 brass with and without arsenic decreases,the strength and hardness of boron-modified brass increase.On the basis of experimental results,the optimum amount of boron in HAl 77-2 brass was found. |
