Hydrodynamic multi-phase model for simulation of laser-induced non-equilibrium phase transformations
A hydrodynamic model based on transport equations and semi-empirical multiphase equations-of-state for metals is developed and applied to simulation of short pulse laser melting and resolidification. New computational algorithms are developed for modeling of two-phase zones of solid-liquid and liquid-gas coexistence, as well as for explicit tracking of interfaces between the phases. The model a...
متن کاملPhase Transformations and Entropy of Non - Equilibrium Materials
The importance of vibrational entropy to solid-state phase transformations has become well established over the past decade. Considerable experimental and theoretical work has gone into investigating the vibrational entropy of phase transformations in metallic alloys. This thesis examines phase transitions in three unique systems, unified in the experimental tools used to probe the nature of th...
متن کاملBoundary-Induced Phase Transitions in Equilibrium and Non-Equilibrium Systems
Boundary conditions may change the phase diagram of non-equilibrium statistical systems like the one-dimensional asymmetric simple exclusion process with and without particle number conservation. Using the quantum Hamiltonian approach, the model is mapped onto an XXZ quantum chain and solved using the Bethe ansatz. This system is related to a two-dimensional vertex model in thermal equilibrium....
متن کاملNon-equilibrium phase transitions
These lecture notes give a basic introduction to the physics of phase transitions under non-equilibrium conditions. The notes start with a general introduction to non-equilibrium statistical mechanics followed by four parts. The first one discusses the universality class of directed percolation, which plays a similar role as the Ising model in equilibrium statistical physics. The second one giv...
متن کاملHeat and Mass Transfer in Pulsed-Laser-Induced Phase Transformations
In terms of heat transfer, the fundamental question raised in this chapter is whether essential features of pulsed laser melting and resolidification at the nanosecond time scale can be described using a thermal model. Of specific interest is the description of the transient melting front propagation as a function of the induced temperature field. Several techniques have been developed to probe...
