摘要最近在伊朗西部的考古发掘中发现了一座位于Seimaleh河旁的萨珊王朝宫殿，名为Ghaleh Guri（Qela Gowri）。作为遗址考古研究的一部分，对五件金属物品（一枚硬币、一个圆盘、一个容器、一个装饰条和一些没有特定功能的物品）进行了取样，并使用OM和SEM-EDS进行了分析，以确定合金成分和微观结构。结果表明，金属条为铜，金属盘、容器和不明物为锡青铜，硬币为银铜合金。容器中的锡含量约为30重量%，可归类为高锡青铜。样品的显微组织还显示，加工量和热处理是可变的，很可能是由于它们的不同成分。
ABSTRACT Recent archaeological excavation in western Iran discovered a Sasanian palace called Ghaleh Guri (Qela Gowri) beside of the Seimarreh River. As part of the archaeometric studies on the site, five metallic objects (a coin, a disc, a vessel, a decorated strip and some pieces with no specific function) were sampled and analysed using OM and SEM-EDS to determine alloy composition and microstructure. The results showed that strip is made of copper, disc, vessel and unidentifiable object are tin bronze and the coin is made of silver-copper alloy. Tin content in the vessel is about 30 wt% and may be classified as high-tin bronze. The microstructure of samples also revealed that the amount of working and the heat treatment was variable, most likely due to their different compositions.
