錫青銅之鑄造與退火實驗研究

Abstract

從中國歷史來看，青銅器的使用時間約1500年，雖然世界各地都有青銅器物的出土，但無論是數量、形制還是工藝，都遠不及中國，因此，對於研究青銅器的材料，中國豐富了許多，但也更加複雜。 本篇文章想藉由模擬實驗，自製青銅錠，並進行分析，想藉由分析結果與分析過後的古青銅器物作比對，試著還原古青銅器物的製作條件。 從本實驗樣品金相組織來看，銅重量百分比超過80%（包含80%），樹枝狀組織顯著。 對樣品Cu80-Sn20樣品的退火實驗來看，在低溫600℃的退火，金相組織由樹枝狀變為粒狀，但退火時間超過20小時，金相組織沒有明顯變化；在高溫780℃退火、水中冷卻的實驗，樹枝狀組織消失，組織逐漸均勻化。From the the Chinese historical point of view, the use of bronze time around 1500, although parts of the world have unearthed bronze objects, but regardless of the number, shape or process, are nowhere near China material for research bronzes enriched many, but also more complex. In this article, we would like the simulation experiments, homemade bronze ingot, and analysis, would like for comparison by the analysis of the results after the analysis of ancient bronze objects, try to restore the production conditions of the ancient bronze objects. From the present experimental sample microstructure point of view, the copper weight percentage exceeds 80% (including 80%), dendritic structure significantly.On of samples Cu80-Sn20 sample annealing experiments at low temperature of 600 ° C annealing, the microstructure changes from dendritic to grainy, but the annealing time is over 20 hours, there is no significant change in the microstructure; 780 ℃ annealing at high temperatureswater-cooling experiments, the dendritic structure disappeared, homogenized tissue gradually
