Institute of Metal Research,Chinese Academy of Sciences,Shenyang 110015

Abstract:The microstructure and properties of boron-modified copper-base alloys were investi-gated by tension,corrosion,corrosive wear and erosion tests. The results show that by adding boron in  copper-base alloys .the strength and hardness of alloys increase,the plasticity decreases somewhat;the  corrosion, corrosive weal and erosion resistance of boron-modified copper-base alloys improve obvious-ly. 'rhe microalloying mechanism of boron in copper-base alloys was found

 

Key words: boron  copper-base alloys  microalloying
