无氧铜含氧量金相检验过去都是采用苏修标准,该标准是五十年代的,方法落后,准确度低,对微量的氧很难检查出来,根本满足不了飞速发展的电子工业部门对材料的要求。我们遵照毛主席关于“打破洋框框,走自己工业发展的道路。”的伟大教导,高举鞍钢宪法伟大红旗,与有关兄弟单位共同努力,制定了我国电真空器件无氧铜含氧量金相检验标准(YB731-
Oxygen-free copper oxygen metallographic examination in the past are used Su repair standards, the standard is the fifties, the method is backward, low accuracy, trace oxygen is difficult to check out, simply can not meet the rapid development of the electronics industry sector Material requirements. In accordance with Chairman Mao’s great teaching on breaking the ocean and taking the path of his industrial development, we hold high the Great Red Flag of the Ansteel Constitution, make joint efforts with relevant fraternal units and formulate the oxygen-free copper oxygen-containing gold Phase inspection standards (YB731-
