Journal ArticleDOI
3D microstructural reconstruction of heterogeneous materials from 2D cross sections: A modified phase-recovery algorithm
Ali Hasanabadi,Majid Baniassadi,Majid Baniassadi,Karen Abrinia,Masoud Safdari,Hamid Garmestani +5 more
TL;DR: In this article, a method for the 3D reconstruction of a microstructure from limited statistical information provided by 2D cross-sections is developed, which relies mainly on conditional probability theorem to establish explicit functional forms between two-point correlation functions extracted from two-dimensional cross sections and full-set 3D statistics.
Journal ArticleDOI
Conductivity and mixed conductivity of a novel dense diffusion barrier and the sensing properties of limiting current oxygen sensors
TL;DR: First-principles calculations were used to explore the effect of various Y-doping levels on the electrical conductivity of SrTiO3 to demonstrate a direct relationship between limiting current (IL) and oxygen content.
Journal ArticleDOI
Evolution of dislocation density and character in hot rolled titanium determined by X-ray diffraction
I. C. Dragomir,Dongsheng Li,G.A. Castello-Branco,G.A. Castello-Branco,Hamid Garmestani,R. L. Snyder,Gábor Ribárik,Tamás Ungár +7 more
TL;DR: In this paper, X-ray peak profile analysis was employed to determine the evolution dislocation density and dislocations type in hot rolled commercially pure titanium specimens, and a good agreement was found between the texture evolution and changes in dislocation slip system activity during the deformation process.
Journal ArticleDOI
Analytical Modeling of Part Porosity in Metal Additive Manufacturing
TL;DR: In this paper, a physics-based model was proposed to predict the part porosity in powder bed metal additive manufacturing (PBMAM) per given process parameters, materials properties, powder size distribution.
Journal ArticleDOI
Diffusion kinetics mechanism of oxygen ion in dense diffusion barrier limiting current oxygen sensors
Ke Shan,Zhong-Zhou Yi,Xi-Tao Yin,Lirong Cui,Davoud Dastan,Hamid Garmestani,Faisal M. Alamgir +6 more
TL;DR: In this paper, B-site deficient yttrium and iron co-doped strontium titanate composites have been prepared and their physical properties were investigated in details.
