Grain-scale modeling of additively manufactured aluminum alloys

Autor: E. Emelianova, M. Pisarev, E. Dymnich, Olga Zinovieva

Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON PHYSICAL MESOMECHANICS. MATERIALS WITH MULTILEVEL HIERARCHICAL STRUCTURE AND INTELLIGENT MANUFACTURING TECHNOLOGY.

In this work, grain-scale simulations of the deformation behavior of an AlSi10Mg alloy produced by selective laser melting are performed. The simulations involve the development of geometrical models of Al-Si eutectic and α-Al dendritic structures w

Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON PHYSICAL MESOMECHANICS. MATERIALS WITH MULTILEVEL HIERARCHICAL STRUCTURE AND INTELLIGENT MANUFACTURING TECHNOLOGY.

In this paper, a method of step-by-step packing (SSP) is used for constructing a 3D grain model of an additive aluminum alloy. The main idea of the SSP is to pack a pre-meshed volume with 3D microstructure elements in a stepwise manner in accordance
