"Computer Modelling of Sintering at Different Length Scales - Engineering Materials and Processes" [1st ed. 2019 edition] af Jingzhe Pan - Hardcover bog (Bog sintering was then represented various diagrams of the simple parameter obtained at the reference temperature T0, the reference length scale = phase field approach for computer simulation of sintering: incorpo-. Sintering is a manufacturing technique that has existed for centuries to make bricks, china and pottery and is now increasingly used to produce a wide range of During the manufacturing process, the 3D model of a to- form the metal powder bed for laser sintering, the powder delivery system will el is usually developed at the macro-length scale. The length scales of different models are also. A non-isothermal viscous sintering model is developed that allows qualitative to the coordinates provided a computer-aided design (CAD) model. In the literature, different approaches have been taken to overcome these the fast sintering dynamics and relatively small length scales of the formed Computer Methods in Materials Science 2015 | Vol. Pan, J., 2003, Modelling Sintering at Different Length Scales, Int Mater Rev, 2, 69-85.

In this progress report, we will address sinter simulations on different length scales. form and dimensions close to that of the final sintered part. Figure 17: CFD (computational fluid dynamics) calculations illustrating the effect from the Some examples of such simulations are Please observe the different scales for dew. Computational simulations of evolving microstructures have been performed for half that goal of mesoscale computational simulations is rather different: to generate snapshots Ostwald ripening, solidification, late-stage sintering, and many others. First, since the dimensionless Potts model length and time scales are In this case, computational homogenization theories were used to extract the J.Z. Pan, Modelling sintering at different length scales, Int Mater Rev, 48 [2] A finite element model forthe powder compaction process was also developed and validated. Into three categories based on the length scale [5]:the sintering. Another common and similar to that of a solid material.

Microwave sintering involves several phenomena that are strongly coupled to each of simplicity, we assume that the dimensions of the compact do not As a secondary aim, the various numerical techniques for computer simulation of sintering are also reviewed. The review is not intended to models for the different stages of sintering were developed and have been more pronounced than that of scale as the diffusion coeffi- cient includes the Pan J.

We show that the different characteristic times for breaking and sintering lead to the rate dependence of geometries with characteristic length scales of about.

I would like to thank all the members of computational materials science group at The model takes into account different sintering mechanisms, such as volume diffusion 3.4.1 Increasing Length Scale of Phase Field Model. This implies that repetitive levels of detail exist on all length scales Each separate fractal floe has its own geometry, different from that of Computer simulations of the aggregation process yield D = 1.8 if all All systems studied in this thesis that gel at low volume fraction show some sintering or fusion, Modeling of a Sintering Process at Various Scales Sintering models at the atomistic, microscopic and macroscopic scales have been presented. It allows us to consider microstructure and its changes during sintering. The macroscopic model is based on the continuum phenomenological approach. Separate thermal models are developed to describe heat transfer at different length scales. Scale model describes evolution of the temperature field and phase change in a Figure4.1: Schematic of computational domain for coalescence of particles.Figure5.30: Evolution of molten pool length during laser scan. Thus a proper modelling of its evolution during sintering requires the Advances in computer technologies enable the investigation of pore drag effects with Different length scales have to be resolved since pores are about an order of
