An Overview of Master Sintering Curve
Applied Mechanics and Materials, 2012The 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.

Linearization of Master Sintering Curve
Journal of the American Ceramic Society, 2009The 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

Austenitic Cladding and Master Curve
Volume 1B: Codes and Standards, 2015Reactor pressure vessels of PWR/BWR/WWER type reactors are covered by austenitic cladding made by welding on their inner wall. Austenitic materials usually have no transition temperature behavior as they have fcc crystallographic structure. But, austenitic cladding made by welding contain usually up to 8 % of delta-ferrite that results in some ...

A Micromechanical Evaluation of the Master Curve
2000The cleavage fracture model of Wallin et al. [1] suggests that the variation of median and bounding values of fracture toughness with temperature is predictable on a micro-mechanical basis. ASTM has recently adopted a standard [ASTM Standard Test Method for the Determination of Reference Temperature, To, for Ferritic Steels in the Transition Range (E ...

The master curve method: a new concept for brittle fracture
International Journal of Materials and Product Technology, 1999The term fracture toughness usually refers to the linear elastic fracture resistance parameter KIC. In the case of structural steels. The estimation of KIC is limited to the lower shelf of toughness or requires extremely large specimens. This specimen size requirement has been one major obstacle for applying fracture mechanics in structural integrity ...

Refinement of Master Densification Curves for Sintering of Titanium
Metallurgical and Materials Transactions A, 2010An 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 ...

A New Scheme of Finding the Master Sintering Curve
Journal of the American Ceramic Society, 2006The master sintering curve approach represents densification data in terms of a master variable that combines sintering time and temperature. Recently, a finite‐element scheme to predict sintering deformation that requires only the master sintering curve instead of a full constitutive law as the input data has been developed. Here,

A cleavage toughness master curve model
Journal of Nuclear Materials, 2000Abstract Development of fusion power will require a fracture toughness database, derived largely from small specimen tests, closely integrated with methods to assess first wall and blanket structural integrities. A master curve-shift (MC–ΔT) method has been proposed as an engineering expedient to treat the effects of structural geometry, irradiation,

A Master Thrust‐Curve for Airscrews
Aircraft Engineering and Aerospace Technology, 1944THOSE engaged on airscrew work are constantly making use of the tables of experimental values of kT and kQ for different values of J given in R.M. 1673. In using these tables it is usually necessary to extrapolate. It is the object of this article to show that, where we have strict grounds for comparison, we can construct a single thrust curve, which ...

A critique of master sintering curve analysis
Journal of the European Ceramic Society, 2018Abstract 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.
