A coupled temperature-displacement phase field model for grain growth during laser-aided metal deposition
Autor: Fikret Kh. Mirzade
Publikováno v: 3D Printed Optics and Additive Photonic Manufacturing.
Laser metal deposition (LMD) by powder injection is an attractive and innovative additive manufacturing of metals. The key to predict material properties is the state of microstructure. In this paper, we develop a thermodynamically consistent tempera

On numerical modeling of heat transfer and fluid flow in selective laser melting of metal powder bed
Autor: Fikret Kh. Mirzade, A. V. Dubrov, V. D. Dubrov
Publikováno v: 3D Printed Optics and Additive Photonic Manufacturing.
Selective laser melting (SLM) of the powder bed is one of the promising techniques for additive manufacturing of metals. Laser powder bed fusion is an inherently multiscale process and calls for an approach using multiple coupled models. In this work

On multi-scale modelling of dendrite growth during laser metal deposition process
Autor: Fikret Kh. Mirzade, V. D. Dubrov, A. V. Dubrov
Publikováno v: 3D Printed Optics and Additive Photonic Manufacturing.
A numerical study of the influence of macroscopic processes of heat and mass transfer on the dendrites formation during laser metal deposition is carried out in the paper. The algorithm used to calculate the processes realizes the concept of multisca

Plane wave propagation in transversely isotropic laser-excited solids
Autor: Fikret Kh. Mirzade
Publikováno v: Physica B: Condensed Matter. 461:17-22
This paper concentrates on the study of body harmonic wave propagation in an anisotropic laser-excited solid in the context of the model based on coupled equations for the displacement and atomic defect concentration fields. The complex secular equat

Features of the estimation of temperature distribution on the bead formed by the laser aided metal powder deposition
Autor: V. D. Dubrov, Fikret Kh. Mirzade, Yuri N. Zavalov, A. V. Dubrov
Publikováno v: Optical Measurement Systems for Industrial Inspection X.
The estimation of temperature variations in five regions of layer track is fulfilled in two different cases of layer track formation: laser aided metal powder deposition and selective laser melting with a pre-deposited layer of metal powder. The pecu
