Computer simulation of sintering processes
Acta Metallurgica, 1979A 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.

AbstractThe sintering process has a special importance for three technical disciplines: powder metallurgy, ceramics, and the agglomeration of ore fines (pelletising). All these methods have been operated empirically for some time, without obtaining a deeper insight into the nature of the process.

Sintering dense NiZn ferrite by two-step sintering process
Journal of Applied Physics, 2011A two-step sintering process has been adopted to produce NiZn ferrite with composition of (NiO)0.35(ZnO)0.57(CuO)0.08(Fe2O3). The densification, microstructure, and magnetic properties of the ferrite have been investigated and compared with those of ferrites produced by the traditional final-stage sintering process.

Plasma Sintering: A Novel Process for Sintering Metallic Components
Materials Science Forum, 1998Metallic components have been sintered in the presence of an abnormal glow discharge. The sample, which works as the cathode of the discharge, is heated by the bombardment of strongly accelerated ions and fast neutrals created in the cathode sheath. The components are sintered at 1120 °C during 20 minutes.

Centrifugal Sintering - Development of a New Pressure Sintering Process -
Advanced Materials Research, 2006Centrifugal sintering is a novel process for the preparation of thick films. In this process, high gravity such as 104g is applied at high temperatures. Because of the distinctive measure of pressing by the centrifugal force, gradient of pressure arises in the specimen, resulting in the graded porous structure during the progress of sintering.

Numerical investigation of sinter cooling process in sinter cooler
AIP Conference Proceedings, 2013In this paper, the sinter cooling process is numerically studied to get the pressure field, velocity field and temperature field when the fluid flows through the porous media by developing a two-dimensional unsteady state computational model. The inlet velocity, layer height, porosity and sinter layer distribution are the main parameters affecting the ...

Modeling Inherently Homogeneous Sintering Processes
Advanced Theory and Simulations, 2018AbstractA novel Monte Carlo model for the simulation of sintering processes is introduced. Different from previous models, local interface curvature is considered in the acceptance of diffusion steps. This enables the investigation of the effects of interface energies on the sintering process.

Sintering Processing of Compressor Flanges
Materials Science Forum, 2007To manufacture a flange for a compressor with a relief groove by using powder metallurgy in order to prevent deformation to the compressor in operation, powder material for the flange is charged into a mold; an ablative member having a melting point lower than that of the powder material is positioned at a place where a relief groove is to be formed ...
