晋阳古城罗城“东马地”遗址出土铁铤铜镞的技术研究

Technological Study on the Iron Collar Copper Arrowheads Unearthed in "Dong Ma Di" Site,Luo Cheng,Ancient City of Jinyang

晋阳古城遗址位于山西省太原市西南晋源区晋源镇所辖19个自然村范围内,面积20余平方公里。2013-2015年晋阳古城考古队在古城罗城"东马地"遗址发掘出土了大量的箭镞。本文采用金相显微镜、扫描电子显微镜(SEM)和X射线能谱分析仪(EDS)对出土的37件铁铤铜镞样品进行检测分析,实验表明这些箭镞均为铸造成型。铜质部分主要合金类型为铜锡铅合金和铜锡合金,铤部均为铁质,大多数已锈蚀。实验结果为研究晋阳地区古代箭镞的制作工艺提供了重要的资料。

Jinyang ancient city ruins is located in the southwest of Taiyuan city, Shanxi province, which within the scope of 19 natural villages in Jinyuan Town. Its area about 20 square kilometers. The archaeological team of Jinyang ancient city excavated amount of metal arrows in the ＂dong ma di＂ of luocheng site from 2013 to 2015.In this paper, the chemical composition and microstructure of 37 metal arrows samples were examined by optical microscopy ~ scanning electron microscopy （SEM）and energy dispersive X-ray analysis （EDS）.The results indicated that most of the iron prats were corrosion, the main alloy type of the arrowheads and arrow shafts were copper-tin alloy and copper- tin-lead alloy by means of casting. These findings supplied important information to realize the manufacture of ancient arrows unearthed from Jinyang region.
