【摘要】 为探讨高句丽铁器加工业发展状况以及魏晋南北朝时期钢铁技术水平,利用金相显微镜对吉林省集安市丸都山城遗址出土铁器样品进行金相学检测及工艺研究,并结合以往高句丽铁器检测结果进行讨论。检测结果表明,工匠制造铁器时采用了"生铁淋口"、铸造后脱碳退火、铸铁脱碳钢材料锻打成型、锋刃部淬火、熟铁、低碳钢等不同材质的锻接、折叠锻打等加工技术。铁镞03JWN2T105②:12是迄今为止应用"生铁淋口"工艺的最早实例,将这种工艺的使用年代,前推至魏晋南北朝时期,相对于明代文献的明确记载提前1000年左右,相对于已报道的宋代实例早600余年,其发明时间应该还在此之前,该项发现对构建魏晋南北朝时期钢铁技术发展序列,具有十分重要的意义。更多还原

【Abstract】 This paper describes studies,using a metallurgical microscope,on metallography,microstructure and technology of the iron and steel artifacts excavated from Wandu Mountain city of Gaogouli,and sheds light on the level of development in the metalwork industry of Gaogouli and on steel and iron techniques used during the Wei,Jin,Southern and Northern Dynasties.The results have been compared with past research on Gaogouli iron objects and show that technologies used by craftsman include: pouring liquid pig iron on edge of iron object(Chinese name: "Sheng Tie Lin Kou"),pig iron decarbornization and annealing after casting to obtain steel and malleable cast iron,steel and folding of steel and wrought iron together to form composite artifacts.The arrowhead 03JWN2T105②:12 is the earliest example of "Sheng Tie Lin Kou" technology so far,and therefore the skill can be dated at least as far back as the Wei,Jin,Southern and Northern Dynasties.This discovery suggests that the technique existed about 1000 years earlier than recorded in literature of the Ming Dynasty,and over 600 years earlier than report for a Song Dynasty object.The invention of the technique could be even earlier.This discovery is crucial to understanding the development of steel and iron technology from Han Dynasty to Wei,Jin,Southern and Northern Dynasties.更多还原
