【摘要】 根据微量多元合金元素交互作用的强化原则 ,研究了一种无Co低Be的CuNiBeCrZr合金。其成本低 ,获得的性能优于价格昂贵的CuCo2Be合金 ,成功地应用于制作我国近几年从国外进口的全自动、高速电阻焊制罐生产线上的无汞焊轮 ,而且是一种性能优异的电阻焊电极合金。本文较为系统地研究了该合金的热处理工艺与其组织和性能之间的关系及其强化的机理 ,为该合金的推广提供了参考更多还原

【Abstract】 A new CuNiBeCrZr alloy without Co and with low Be was developed through multi element micro alloying,and was successfully used in welding wheel of the all automatic and high speed electric resistance welding can be used in production line without Hg which was imported recently.The properties of this alloy are superior to that of CuCo2Be alloy with lower cost,it is also an excellent electric resistance welding electrode alloy.The effects of heat treatment process to the microstructure and properties,and its strengthening mechanism were systematically researched,and it is helpful to its wide use.更多还原
