A critique of master sintering curve analysis

Journal of the European Ceramic Society, 2018
Abstract In this work, we explore factors affecting the accuracy of the master sintering curve (MSC) approach for analyzing the complete sintering profile of ceramic powders. We show that the instantaneous anisotropic shrinkage must be accounted for to develop an accurate MSC.

A differentiating approach to the master sintering curve analysis

Ceramics International, 2020
Abstract The master sintering curve (MSC) has been widely applied in analyzing and predicting the densification process during sintering. The usual approach to the MSC analysis supposes that the apparent activation energy of sintering Q keeps constant during the whole sintering process, but some studies reported that the density influenced Q.

Master sintering curve and activation energy of sintering of ZrO2-doped Al2O3

Ceramics International, 2021
Abstract Master sintering curve (MSC) was used to make an estimation of the apparent activation energies of undoped Al2O3 and ZrO2-doped Al2O3 samples in the intermediate density range (60–83%). ZrO2 at low concentrations of 2000 ppm and 5000 ppm were used for doping Al2O3. Dilatometric studies were performed using three different heating rates (5, 7.

Two-stage master sintering curve applied to two-step sintering of oxide ceramics

Journal of the European Ceramic Society, 2013
Abstract Tetragonal (3 mol% Y2O3) and two cubic zirconia (8 mol% Y2O3) as well as alumina green bodies were used for the construction of the Master Sintering Curve (MSC) created from sets of constant-rate-of-heating (CRH) sintering experiments. The activation energies calculated according to the MSC theory were 770 kJ/mol for Al2O3, 1270 kJ/mol for t-

Densification evolution of TiO2 ceramics during sintering based on the master sintering curve theory

Materials Letters, 2008
Abstract The Master Sintering Curve (MSC) of rutile TiO 2 was constructed using constant heating rate dilatometry data based on the combined-stages sintering model. The present research was carried out to predict and control densification evolution of TiO 2 ceramics during pressureless sintering. Densification of TiO 2 was continuously recorded at

Linearization of Master Sintering Curve

Journal of the American Ceramic Society, 2009
The master sintering curve (MSC) is a simple and functional sinter model that is used to describe the densification of a particulate material during sintering when one sintering mechanism is dominant. Usually the MSC is expressed mathematically by a sigmoid relationship between the natural logarithm of the work of sintering and the

An Overview of Master Sintering Curve

Applied Mechanics and Materials, 2012
The search for a simple, accurate model to predict the sintering behavior is still a valid challenge facing the particulate materials industry. In spite of the sophistication of the before proposed methods, most models have not yet attained a desirable level of applicability.

Master Sintering Curve: A Practical Approach to Sintering

Journal of the American Ceramic Society, 1996
One of the ultimate objectives for sintering studies is to be able to predict densiflcation results under different thermal histories for a given processing method. It has been reported that the geometric parameters related to sintering often are functions only of density for a given powder and green‐body process, provided that one

Refinement of Master Densification Curves for Sintering of Titanium

Metallurgical and Materials Transactions A, 2010
An approximate master curve for the densification of cold-pressed titanium powder during vacuum sintering was published previously. It was based on the combined results for three different titanium powders. The master densification curve model incorporates the effects of particle size, compaction pressure, sintering time, and sintering temperature on ...
