摘　　要：为了解中国古滇地区铜铁农具、兵器和工具的制作工艺,采用金相显微镜组织观察和扫描电子显微镜分析的方法,对昆明呈贡天子庙和呈贡石碑村出土的战国至西汉时代11件铜器和2件铁器样品进行分析。分析结果表明,铜器的材质有红铜和铜锡合金两种,相同的器物有较稳定的化学成分。铜器中农具、兵器和工具为铸造制作而成。2件铜柄铁刃剑的材质为亚共析钢,作为兵器,具有优良的性能。本研究成果对进一步研究古滇地区铜铁器具的工艺技术有一定的价值。Eleven copper alloy and two iron artifacts, dating from the Warring States period to West Han Dynasty, and unearthed from Chenggong Tianzimiao and Chenggong Shibeicun, Kunming, were analyzed by optical and scanning electron microscopy. Copper and Cu - Sn alloy were identified, and the chemical composition was similar for similar objects. The copper - made farm implements, weapons and tools were made by casting and showed no sign of usage. Two iron blade swords with bronze handles had been made of hypoeuteetoid steel, which was a good quality for weapons.
