Abstract
A phase field model that includes the stress field during non-isothermal solidification of a one-component system has been developed. The model has been applied to solidification and melting of confined spherical volumes. It has been shown that at some boundary and initial conditions the evolution of a spherically symmetric system results in isothermal steady states with a time-independent distribution of phase. The temperature interval of two-phase stability decreases with the sphere radius. The presented model can be applied to simulate the process of “writing” to electronic media that exploit an amorphous-to-crystalline phase change for recording information.
