中国古代铜器的显微组织

Microstructure of Ancient Chinese Copper Artefacts

总结了２８年来作者对中国考古发掘出土逾千件铜器显微组织的研究成果，表明：中国古代铜及铜合金有纯铜、砷铜、锡青铜、铅青铜、铅锡青铜、黄铜、铅黄铜、银铜、砷白铜及镍白铜等；它们的显微组织显示了铸造、冷热加工组织以及室温长期埋藏条件下铜合金组织发生的变化，以及不同时代、不同地区显示的特征等；与现代铜及铜合金金相图谱有诸多不同．这些研究成果丰富了铜及铜合金金相学的内容．

Over one thousand samples which was acquired from original excavation sites provided abun- dant speciments for the microstructure study of ancient Chinese copper arntefacts. The results show that the materials of ancient Chinese copper include pure copper, arsenic copper,lead bronze, lead-tin bronze, brass, lead brass, silver copper, arsenic paktong and nickel paktong, etc. The microstructure of ancient Chinese cop- per artefacts illustrate the casting structure of different composition, working structure including hot working and cold working and unusual cases, which differ from those of the modem copper alloys.
