^MICROSTRUCTURE AND MECHANICAL PROPERTIES OF BORON-MODIFIED HAI 77-2 BRASS

WANG Jihui;JIANG Hiaoxia;LI Shizhuo(Institute of Metal Research,Chinese Academy of Sciences.Shenyang 110015)  
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.
