超快差示扫描量热仪是第三代差热分析技术, 可以实现最高60000 K/s的超快速加热和最高40000 K/s的超快速冷却, 适合对熔点小于1000 ℃的物质或材料进行速率跨越五个数量级的反复原位升降温测试. 该仪器独特的高速率在满足人们观测样品中毫秒尺度上的结构转变需求的同时, 也产生大量的数据. 本文提出一种“俯视图”的数据分析方法, 即将热流投影到温度-速率或温度-时间的平面, 然后用颜色衬度代表热流强弱. 该方法有效地解决速率或时间在“侧视图”上难以被区分和量化的问题, 实现同时观测几个物理现象和比较其动力学行为的目的. 本文以一种Au基非晶合金为例, 从4篇代表性文献中的“侧视图”上采集数据, 重新绘制出“俯视图”, 比较两者的优缺点. 上述方法具有普适性, 适合对任何物质或材料的超快差示扫描量热数据进行分析. 不仅如此, “俯视图”也为构建新材料的工艺相图、发现新的结构转变和探索不同物理现象的动力学行为提供支持和帮助. 本文数据集可在https://doi.org/10.57760/sciencedb.j00213.00012中访问获取.Ultrafast differential scanning calorimetry is the third-generation technique of differential thermal-analysis. It can fast heat up to 60000 K/s or fast cool down to 40000 K/s, so its temperature-changing rate spans five orders of magnitude, and permit repeating experiments on compounds or materials with a melting point lower than 1000 ℃. The unique rate of temperature change allows it to record structural changes of sample in milliseconds, producing a significant number of data. A “top-view” graph is suggested in this study for data analysis. It basically projects the heat flow onto a plane of variables such as temperature, rate or time and uses color contrast to describe the intensity change of heat flow. The issues with “side-view” graphs, where it is a challenge to discern rate or time from several curves, are successfully resolved by this novel technique. It can also realize a comparison of the kinetics among several co-existing physical events. Using an Au-based metallic glass as an example material, this work collects the data from four “side-view” graphs in literature, replots the data on “top-view” graphs, and compares pros and cons. Any substance or material to be examined by utilizing fast differential scanning calorimetry can be examined through using the “top-view” approach. It is useful not only for data analysis but also for constructing processing maps for novel materials, finding new structural transitions, and examining the kinetic behaviors of physical phenomena. All the data presented in this paper are openly available at https://doi.org/ 10.57760/sciencedb.j00213.00012.
