| Abstract: |
| The alloy composition and metallographic microstructure of twelve bronzes excavated from Zhangdazhong Cemetery of Chu State in the Warring States Period at Yutai Village in Jinan Town, Jinzhou City, Hubei province, were analyzed by the metallographic microscope and XRF. The results show that these bronzes are made of copper-tin-lead, copper-lead-tin and copper-tin alloys, and lead-tin and tin-lead bronzes contain high level of lead. Most of them are foundry products and two bronze plates are made by hot forging. Meanwhile, there are more differences in the alloy compositions and metallographic microstructures with different types and functions of the bronzes. Although the Zhangdazhong Cemetery is the cemetery of the lower nobility of the Chu State in the middle and late Warring States period, the alloy, manufacturing technology and mechanical properties of some simple and badly corroded bronze vessels demonstrate that craftsmen of the Chu State have mastered superb bronze alloy, casting and processing technologies, which also reveals that craftsmen intentionally adjust the alloy between bronze burials and vessels. The result of the study can provide important clues to recognize fully the development status of the bronze production industry in the Ji''nan City of the Chu Capital during the Eastern Zhou Dynasty. |
