Computer simulation of sintering processes

Acta Metallurgica, 1979
A numerical procedure is described for simulating sintering of model systems. Based on earlier work by Nichols for surface diffusion transport, simultaneously acting mechanisms (surface and grainboundary diffusion) are treated without simplifying assumptions concerning the neck geometry developed during sintering.

Microwave Sintering Process Model

Journal of Microwave Power and Electromagnetic Energy, 2003
In order to simulate and optimize the microwave sintering of a silicon nitride and tungsten carbide/cobalt toolbits process, a microwave sintering process model has been built. A cylindrical sintering furnace was used containing a heat insulating layer, a susceptor layer, and an alumina tube containing the green toolbit parts between parallel ...

Dislocation Activated Sintering Processes

Powder Metallurgy, 1985
Using sphere-plate models made from copper it is shown that during sintering the dislocation density increases considerably in the contact region. Its distribution and time dependent variation can be analysed by means of the Rossel technique and described quantitatively.

Sintering Process Control

IFAC Proceedings Volumes, 1998
Abstract Sinter is basic metallic charging material for most blast furnaces. Sintering process reengineering can significantly influence sinter mechanical and metallurgical properties. This paper presents improvements of the sintering process and process optimal control.

Completion of the sintering process

Ferrous Metallurgy. Bulletin of Scientific , Technical and Economic Information
The process of sintering is completed only on sinter machines with a cooling zone. The degree of completion of the process, characterized by the relative height of the melt zone during unloading of the sinter from other types of machines, which make up the absolute majority, is at the level of 60%. In practice, the “completion of the sintering process”

PROCESSES INVOLVED IN SINTERING

Powder Metallurgy, 1959
1.-INTRODUCTION THE considerable advances in powder metallurgy during the past two decades call for a knowledge of, and an ability to interpret, the physicochemical processes that control sintering. This need has stimulated a large amount of experimental and theoretical research in an attempt to establish the laws governing sintering, but this ...

Characteristics of sintering processes

Soviet Powder Metallurgy and Metal Ceramics, 1978
New, more accurate formulations of the autonomy and stress transfer principles are proposed. Quantitative characteristics of autonomy are defined. An examination is made of characteristics determining quantitatively the participation of various types of deformation (with contact fixation or disturbance) in consolidation (sintering, sintering under ...

Volumetric Analysis of a Sinter Process in Time

2005
We present the first fully three dimensional analysis of the sinter process of copper using particles of a realistic size. This has been made possible through the use of μCT. A 3D image processing chain, applied to each time step of this 4D dataset, followed by image registration and particle matching steps was used.
