【摘要】 通过对峡江地区129件青铜器的金相组织与成分分析,初步了解峡江地区战国中晚期至秦汉青铜技术水平。所分析129件青铜器均为锡青铜和铅锡青铜,93%是铸造组织,有6件为热锻组织,3件是热锻后又经过冷加工。有1件是青铜淬火组织。从成分含量、金相组织整体审视这批样品,兵器与工具代表了当时巴地乃至峡江流域的青铜工艺技术的较高水平。技术分析结合型制研究,初步判断峡江出土青铜器以本地制作为主,少量属于外来的。该地区青铜制作技术受到外来文化的影响,但与周边不同步的自身发展仍是该区域的主流。更多还原

【Abstract】 129 bronze samples are studied by scanning electron microscopy and metallography.All the samples are made of Cu-Sn alloy and Cu-Sn-Pb alloy,among which 119 samples are of cast structure,and 9 samples show recrystal grain and twin crystal.Maybe these 9 bronzes were first cast and then forged.Only 1 sample shows β’M-quenching.For the samples with identical cultural background,the components are similar.Compared with Chu-style weapons,the content of Pb in the weapons of Ba-Shu style is lower.Proper content of Sn and Pb enables the weapons and tools to have high hardness and tensile strength.After analysis,it can be seen that most of these bronzes were made in the locality,and a small quantity of them were obtained from other places.These samples present a comparatively high bronze technological level of the Ba and Xiajiang River region.The bronze technology in the Xiajiang River region had its own development.更多还原
