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).
