“…Micromachining. Besides characterizations of workpiece geometries, surface morphologies, microsctructures, and properties after laser micromachining, other important research approaches include in situ time-resolved observations and physics-based modeling to improve the understanding of laser micromachining processes [212][213][214][215][216][217][218][219][220][221][225][226][227][228][229][230][231][232][233][234][235][236][237][238][239].…”

“…For example, Ref. [238] reports a model for ns laser ablation of aluminum by solving hydrodynamic equations, where possible explosive boiling has been considered. Continuum-scale models have the advantage of being able to handle relatively large temporal and spatial scales, but often lack the capability of directly revealing atomic-scale phenomena, which can be potentially described by a molecular dynamics (MD) model for laser ablation.…”

Recent years have witnessed a rapid growth of the laser market. Figure 1 shows the recent revenues of laser sales with about 50% increase in revenue over recent four years , which far exceeds the growth of other industrial sectors. More than one third of this revenue belongs to the category of laser materials processing arena. Undoubtedly, lasers have been playing increasingly important roles in various industrial manufacturing sectors. This article is to capture some of important developments in the rapidly growing areas of laser-based manufacturing and materials processing and also describe important technological issues pertaining to various laser-based manufacturing processes. The topics to be covered in this paper include more popularly used processes in industry such as laser additive manufacturing, laser-assisted machining, laser micromachining, laser forming, laser surface texturing, laser welding, and laser shock peening, although there are several additional areas of laser applications. In each section, a brief overview of the process is provided, followed by critical issues in implementing the process, such as properties, predictive modeling, and process monitoring, and finally some remarks on future issues that can guide researchers and practitioners.

The article presents the results of atomistic modeling of the equilibrium thermophysical properties of gold in a wide temperature range (T~ 0.3–3.50 kK), covering the regions of first-order phase transitions of melting and evaporation. The temperature dependences of the density, linear size of the sample, coefficient of linear expansion, enthalpy, and heat capacity are determined. The obtained dependences of the properties of gold are approximated by polynomials of low degrees. There is an acceptable agreement between the obtained characteristics of gold and the experimental data. Numerical and graphic information on the obtained properties and results of comparison with experimental data is presented.

“…The problem of the adequacy and reliability of simulation results is associated with determining the properties of the target. The information on the temperature dependence of thermal conductivity is a necessary characteristic of a target when modeling laser heating of a substance using continuum models [9]. It is known that in accordance with the classical concepts, in a solid there are two mechanisms of heat transfer: elastic lattice vibrations and free electrons, therefore, thermal conductivity can be represented by lattice and electronic components.…”

In a wide temperature range, including the semiconductor-metal phase transition region and the near-critical region, the results of modeling the silicon phonon thermal conductivity are presented. Since the transfer of thermal energy is carried out by phonons and free charge carriers, it is necessary to take into account both the contribution of phonons and electrons in the total thermal conductivity. In contrast to metals, heat transfer in silicon in the solid state is determined by phonon thermal conductivity. Although the contribution of the electronic component to the total thermal conductivity increases with increasing temperature, the inclusion of phonon thermal conductivity is of particular importance in liquid silicon. At higher temperatures, phonon thermal conductivity plays an important role in the modeling of the mechanisms of interaction of pulsed laser radiation with silicon in the framework of the two-temperature continuum model. Obtaining the temperature dependence of phonon thermal conductivity in such a wide temperature range from experiment is problematic. In this work, phonon thermal conductivity was obtained in the range 300 ≤ T ≤ 6500 K from molecular dynamics simulation using the KIHS potential.
