广富林遗址出土周代青铜器合金成分与金相分析

为了了解上海松江广富林遗址出土周代铜器合金配比和加工工艺特点,对18件该地区出土周代铜器进行检测分析。使用X射线荧光光谱仪(XRF)和金相显微镜分析青铜样品的成分组成及金相显微组织并发现:样品中铅锡青铜器占绝大多数,器物含铅量普遍较高,且大多含少量砷;器物基本都是铸造成形,仅有少量实用工具、农具刃口进行过热锻等加工处理,以提高使用性能。结果反映了当时工匠对铸造合金配比和加工工艺的认知和技术水平,也体现了吴越地区独特的青铜技术体系与文化,能够为南方史前及先秦文化的发展脉络提供更多可供探讨的资料。

Research on the composition of and processing technology for Zhou Dynasty bronze objects unearthed at Guangfulin Site

In our work, we examined over 20 Zhou Dynasty bronze objects including vessels, weapons, farm implements and tools unearthed at the Guangfulin Site in Shanghai. Metallographic microscopy and X-ray fluorescence spectrometry (XRF) were used to analyze the metallographic structure and composition of the alloys. The results were significant in revealing the methods of cast bronze fabrication and processing technology at that time. Based on this work, the methods of alloy composition, casting technology and diffusion of bronze in Shanghai before the Qin Dynasty are reviewed and summarized. It is expected that this work will provide more information for the future research on the development of prehistoric and pre-Qin cultures in southern China.
