Data points of spark plasma sintering behaviour and thermal properties of Ti-Ta-Zr shape memory alloy powders

This data are numerical values of the stages involved during the spark plasma sinteirng (SPS) of Ti-Ta-Zr powders. They captured the densification behaviour and powder densification rates respectively. Also included are the data points obtained from the X-ray diffraction of the polycrystalline alloy that was finally fabricated from the SPS process. Thermal transport behaviour of each sintered products as a function of temperature and material compositions are also captured by this data. The thermal measurements techniques utilized include: thermal diffusivity by laser flash and phase transformation by differential scanning calorimetry.

本数据集收录了Ti-Ta-Zr粉末在放电等离子烧结（Spark Plasma Sintering，SPS）过程中各阶段的数值数据，这些数据分别记录了粉体的致密化行为与致密化速率。数据集还包含通过X射线衍射（X-ray Diffraction，XRD）对经SPS工艺最终制备的多晶合金采集的测试数据点。此外，各烧结试样的热传输特性随温度与材料成分的变化关系也被纳入本数据集。本次研究所采用的热物性测试手段包括：激光闪射法测试热扩散率，以及采用差示扫描量热法（Differential Scanning Calorimetry，DSC）表征相转变行为。
