MICROSTRUCTURE AND PROPERTIES OF BORON-MODIFIED ALUMINIUM BRONZE
加硼铝青铜的组织和性能

The effects of boron on the microstructure,mechanical properties,corrosion and corrosive wear resistance of aluminium bronzes were investigated systematically.The results show that the addition of boron can fine the grain size,increase the strength and hardness of aluminium bronze without greatly affecting its plasticity,the selective corrosion and corrosive wear resistance were also improved.The mechanism of boron in aluminium bronze was discussed.
