I want to simulate solid state sintering of metal powder, conducted under vacuum.
I am interested in the initial stage of sintering, does not matter to reach full density.
Do you know any model or software to perform this simulation?
Good afternoon, Giovanni Rizza!
1. Use the "ANSYS" software and its software modules, which are often used to study (simulate) the fusion and sintering of solid-state elements in a protective atmosphere.
2. Or modeling through "Magics" based on voxel structure.
Good morning and thank you for the answer!
I've checked the solutions you suggested, but I am not interest in simulation of the EB-LPF or L-PBF process, but in sintering in general.
I would like to know if you or other researcher knows the existence of software or models to simulate sintering of two spheres of metal powder.
Good morning B. Melzi
Thank you for the answer. I've already tried with Abaqus to do this kind of simulation, but did not work. In your knowledge, does ANSYS have any module dedicated to sintering simulation?
Dear Giovanni, if you want to describe the process from phenomenological perspective, I believe you can use the Netzsch Neo Kinetics software (https://kinetics.netzsch.com/en/), requiring input dilatometry data for analysis. The sintering process is somewhat a gray area, with a few possible constituent mechanisms. For instance, if you care to look at one of my papers ('On Morphological and Microstructural Changes in Uranium Dioxide Powder during Binder-Free Hot Pressing'), we actually proposed that dislocations introduced at the pressing stage might contribute to the deformation of crystallites at the initial stage of sintering, but we haven't come to a model of the event per se.
