Abstract
| - Mixed n-alkane can change isothermally from the ordered crystal (Φord) to the rotator R state. Thermodynamic analysis of the isothermal data, corresponding to experimental EGC temperatures, results in a successful calculation of the [Φord + R] equilibrium temperatures. We show that the phenomenon corresponds to diffusionless, or martensitic, transitions in metal alloys.
- We show that it is possible to make mixed n-alkane samples to change isothermally fromthe ordered crystal state (Φord) to the rotator state R. This isothermal transition has beenobserved in DSC and X-ray powder diffraction experiments, for all compositions in variousbinary systems, by maintaining mixed samples for a long time in the R state. Thermodynamicanalysis of the isothermal data, which correspond to experimental EGC temperatures, resultsin a successful calculation of the [Φord + R] equilibrium temperatures. The thermodynamicinterpretation and X-ray diffraction observations show that the phenomenon correspondsto diffusionless, or martensitic transitions, in metal alloys.
