摘要
测量了去合金后的掺砷双相黄铜H_(62)As中的正电子寿命,为黄铜优先腐蚀的双空位机制提供了较为直接的实验证据。讨论了掺砷黄铜抑制脱锌的机理。
Positron lifetime in divacancy in de-alloyed arsenic doped brass, H62As, has been measured. This can be regarded as a more direct experimental evidence for the divacancy mechanism of preferential dissolution for brass. The mechanism of resisting preferential dissolution for arsenic doped brass has also been discussed.
