Thermo-physical data for Co-Cr-W and Co-Cr-W-Si-Mn

Cobalt Chrome Tungsten (Co-Cr-W) ternary and micro-alloyed samples (Co-Cr-W-Si-Mn) were manufactured using a Rapid Alloy Prototyping methodology which combined ball milling, powder compaction and induction melting. Each composition selected was studied in three conditions; as-cast, annealed for 4 hrs at 1100°C and annealed for 14 days at 1100°C. The samples were analysed using XRD, Dilatometry, hardness, SEM/EDS and DSC forming a significant chapter of work from Dr Jonathan Cullen's PhD thesis.

CONTENTS OF DATABASE
The database contains all raw data from the measurements and all the microscopy of samples which have not been included in subsequent publications due to space limitation, copyright or data averaging.

For example, the Coefficients of Thermal Expansion (CTE) obtained for individual compositions covered a temperature range from RT to 1100 Deg C, but typically plotted as average CTE values over temperature intervals of 50 deg C . The data in this database contains the complete raw data set.

SAMPLE NUMBERS, COMPOSITION AND PHASES

The sample numbers [1-53] are used throughout this database, for the compositions XX Co – YY Cr – ZZ W (always in weight percentage). Samples for the Co-Cr-W ternary are labelled and saved in folders called CCW, whereas samples microalloyed with Mn or Si are under folders labelled CCWSM.

The CCW samples [1] - [53] are labelled as in excel file at top level folder (Co-Cr-W Summary of Chemistry Hardness and DSC data.xlsx).

The CCWSM samples [1] - [12] are labelled as in excel file at the top level folder (Co-Cr-W-Si-Mn Chemistry CTE Hardness and Enthalpy.xlsx).

钴铬钨（Co-Cr-W）三元合金及微合金化钴铬钨硅锰（Co-Cr-W-Si-Mn）样品采用结合了球磨、粉末压制与感应熔炼的快速合金原型制备（Rapid Alloy Prototyping）工艺制备。每种选定成分的样品均在三种状态下开展测试：铸态、1100℃退火4小时以及1100℃退火14天。研究团队采用X射线衍射（X-ray Diffraction, XRD）、热膨胀测试（Dilatometry）、硬度测试、扫描电镜/能谱分析（Scanning Electron Microscopy/Energy Dispersive X-ray Spectroscopy, SEM/EDS）以及差示扫描量热法（Differential Scanning Calorimetry, DSC）对样品进行表征分析，该数据集是乔纳森·C·T·卡伦博士博士论文中的重要研究章节。

## 数据集内容
本数据集包含所有测试原始数据，以及因篇幅限制、版权问题或数据平均化处理而未在后续发表论文中收录的全部样品显微表征数据。

例如，针对各成分测得的热膨胀系数（Coefficients of Thermal Expansion, CTE）测试温度范围为室温（Room Temperature, RT）至1100℃，但通常仅展示50℃温度区间内的平均热膨胀系数数值。本数据集收录了完整的原始测试数据集。

## 样品编号、成分与物相
本数据集全程使用编号[1-53]对应成分为XX Co – YY Cr – ZZ W（均以质量百分比计）的样品。Co-Cr-W三元合金样品存储于名为CCW的文件夹中，而掺加锰或硅的微合金化样品则存储于名为CCWSM的文件夹内。

编号为[1]-[53]的CCW样品命名规则与顶层文件夹中的Excel文件"Co-Cr-W Summary of Chemistry Hardness and DSC data.xlsx"一致。

编号为[1]-[12]的CCWSM样品命名规则与顶层文件夹中的Excel文件"Co-Cr-W-Si-Mn Chemistry CTE Hardness and Enthalpy.xlsx"一致。
