TL;DR: In this paper, a 3D particulate scale dynamic simulations were carried out to study the spreading of 316L stainless steel powder during printing by using discrete element method (DEM), and the influences of various factors including processing parameters, blade shape, and powder size on the quality of the spread powder bed were investigated in terms of both macroscopic packing density/uniformity and microstructure/micro dynamics.

TL;DR: In this paper, the effects of processing parameters on the macro and microscopic properties of the spread powder beds were systematically investigated, and the results showed that the optimal blade velocity and gap height of 0.01 m/s and 3 D (D90) are preferred for the superior powder bed with high packing density and good uniformity.

TL;DR: In this paper, three-dimensional hot pressing of TiC-316L composite powders in a closed die is numerically reproduced by multi-particle finite element method from particulate scale.

TL;DR: Wang et al. as mentioned in this paper proposed a self-encapsulation strategy of eutectic Al-Si phase change material (PCM) in iron-based encapsulation container to realize the high temperature waste heat recovery in metallurgical industry.

TL;DR: In this paper, a numerical investigation on the 2D uniaxial die compaction of TiC-316L stainless steel composite powders by the multiparticle finite element method (MPFEM) is presented.
