Stability of cobalt?carbon high temperature fixed points doped with iron and platinum

Original language description

High temperature fixed points (HTFPs) are stable and repeatable and make comparison of temperature scales possible at a level of uncertainty not previously possible. However, they potentially lack objectivity if the fixed-point temperature is known. FiveHTFPs were constructed, one pure Co?C, two Co?C doped with Fe and two Co?C doped with Pt of differing concentrations. The candidate dopants were identified through thermochemical modelling as likely to give maximum temperature shift with minimum increase in melting range. The temperature differences of the doped systems from the pure system were determined and it was found that the addition of Fe depressed the melting temperature and the addition of Pt elevated the melting temperature, qualitatively inline with the thermochemical modelling. The higher concentration doped HTFPs were then aged for approximately 100?h with continuous melting?freezing cycles and the difference to the undoped Co?C HTFP remeasured. These differences were fo
