Abstract
A method of analyzing a phase transformation process of a material comprises providing a spherical sample of the material, measuring and recording a first data series of core temperature at the sample's center of gravity, measuring and recording a respective second data series of temperature at the sample's periphery, measuring and recording a respective third data series of radial displacements at the sample's periphery, and calculating a change in pressure in the sample at a plurality of points in time based on first, second and third said data series.

A method of analyzing a phase transformation of a material, comprising:
- providing a spherical sample of the material,
- measuring and recording a first data series of core temperature at the sample's center of gravity,
- measuring and recording a respective second data series of temperature at the sample's periphery,
- measuring and recording a respective third data series of radial displacements at the sample's periphery, and
- calculating a change in pressure in the sample at a plurality of points in time in based on said first, second and third data series, said change in pressure being caused by the phase transformation of the sample.
A device for analyzing a phase transformation of a material, comprising:
- a gripping device for holding a spherical sample of the material,
- a first measuring device for measuring a first data series of core temperature at the sample's center of gravity,
- a second measuring device for measuring a respective second data series of temperature at the sample's periphery,
- a third measuring device for measuring a respective third data series of radial displacements at the sample's periphery, and
- a processing device, arranged to receive the first, second and third data series and for calculating a change in pressure in the sample at a plurality of points in time in based on the first, second and third said data series, said change in pressure being caused by the phase transformation of the sample.
