PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2019 (ICCMSE-2019).
The space in coordinates, the scalar convolution of which contributes to the Gibbs energy or energy, is called the space in conjugate coordinates (CCs), for example, the P -V space (pressure-volume coordinates. The report examines the use of spaces i

It is shown that the presence of dispersion of particles with nano-sizes can lead to the appearance of a local phase transition on the surface layer of a sub-granule or a local bcc / fcc phase transition in pure Fe can occur at the intergranular boun
