Microstructural evolution of simulated heat affected zone and thermomechanical treatment in TMCP steel plate
碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 86 === TMCP(Thermomechanically controlled processed)之生產利用線上加速製程來提高 鋼板的冷卻速率,因此TMCP鋼板組織晶粒細緻均勻,而傳統鋼板的晶粒較粗且波來鐵帶狀 組織明顯。但對TMCP鋼板API 5L X65 的原材觀察可發現,愈接近中心區域波來鐵帶狀組 織愈明顯,經過EPMA的分析得知錳、矽偏析現象嚴重;加上中心區域冷速慢,而形成帶 狀組織。進一步利用...
