Abstract This study describes a method which has been developed to monitor flow and cooling during casting using a high-speed infrared camera. The spatial and temporal resolutions were 60 μm and 1 ms, respectively. Calibration was performed to obtain the local, quantitative temperature history of a wedge-shaped specimen after post processing. Depending on microstructure (amorphous vs. crystalline) a temperature measurement accuracy of ±3 K or ±5 K was achieved. The temperature data recorded for a low-melting Au-based alloy during casting were compared thoroughly with its crystallization kinetics. The high-speed infrared measurements correlate well with fast differential scanning calorimetry (FDSC) results. This emphasizes the great potential of both techniques for studying fundamental processes which occur during casting.

使用高速红外监测和互补快速扫描量热法研究大块金属玻璃铸件

摘要 本研究描述了一种使用高速红外摄像机监测铸造过程中流动和冷却的方法。空间和时间分辨率分别为 60 μm 和 1 ms。进行校准以获得后处理后楔形试样的局部、定量温度历史。根据微观结构（非晶与结晶），温度测量精度达到 ±3 K 或 ±5 K。在铸造过程中记录的低熔点金基合金的温度数据与其结晶动力学进行了彻底的比较。高速红外测量与快速差示扫描量热法 (FDSC) 结果密切相关。这强调了这两种技术在研究铸造过程中发生的基本过程方面的巨大潜力。
