A mathematical approach to Ostwald ripening due to diffusion and deformation in liquid bridge

Autor: Ranđelović B., Shinagawa K., Nikolić Z.S.

Publikováno v: Science of Sintering, Vol 45, Iss 3, Pp 261-271 (2013)

From many experiments with mixtures of small and large grains, it can be concluded that during liquid phase sintering, smaller grains partially dissolve and a solid phase precipitates on the larger grains and grain coarsening occurs. The growth ra

Liquid phase sintering, I: Computer study of skeletal settling and solid phase extrication in a normal gravity environment

Autor: Nikolić Z.S.

Publikováno v: Science of Sintering, Vol 40, Iss 1, Pp 3-12 (2008)

In this paper we will investigate gravity induced skeletal settling during liquid phase sintering. In this approach skeletal settling will be combined with extrication of some solidphase domains. The main goal will be the need to relate dissolution,

Liquid phase sintering, II: Computer study of skeletal settling and solid phase extrication in a microgravity environment

Autor: Nikolić Z.S.

Publikováno v: Science of Sintering, Vol 40, Iss 2, Pp 107-116 (2008)

A two-dimensional numerical method based on the Brownian motion model and on the Densification model for simulation of liquid phase sintering in microgravity environment will be developed. Both models will be based on domain topology (two-dimensional

Basic and mixed models for computer simulation of liquid phase sintering of a porous structure

Autor: Nikolić Z.S.

Publikováno v: Science of Sintering, Vol 39, Iss 1, Pp 3-8 (2007)

A two-dimensional method based on basic and mixed models for simulation of liquid phase sintering of a porous structure will be developed. These models will be tested in order to conduct a study of diffusion phenomena and gravitational effects on mic

Finite difference method for computer study of the interfacial heat transfer coefficient during rapid solidification of spherical samples on a metallic substrate

Autor: Nikolić Z.S., Yoshimura M., Araki S., Fujiwara T.

Publikováno v: Science of Sintering, Vol 39, Iss 2, Pp 111-116 (2007)

In this paper a numerical model will be adopted to analyze the heat transfer process during rapid solidification of a spherical sample placed on a metallic substrate cooled by water. The interfacial heat transfer coefficient between the sample and th

Computer simulation of free settling and skeletal settling during liquid phase sintering

Autor: Nikolić Z.S.

Publikováno v: Science of Sintering, Vol 38, Iss 1, Pp 41-54 (2006)

In recent years, a range of computer simulation models leading to a better understanding of liquid phase sintering phenomena, have been developed with the aim of simulating the detailed evolution of microstructure during grain growth. Some liquid pha
