Texture Classification in Microstructure Images of Advanced Materials

2008 IEEE Southwest Symposium on Image Analysis and Interpretation, 2008
In this paper we discuss texture classification of microstructural images used in the development of advanced materials. Different materials or different phases of a material in a sample lead to different textures in images of that sample. We investigate the application of the expectation-maximization/ maximization of the posterior marginal (EM/MPM ...

Classification and Phylogenetic Significance of Molluscan Shell Microstructure

Notes for a Short Course: Studies in Geology, 1985
Like most classifications of molluscan shell microstructure published during the past 25 years (e.g., MacClintock, 1967; Kobayashi, 1964, 1971; Taylor, Kennedy and Hall, 1969, 1973; Grégoire, 1972a), the present one is based largely on Bøggild's (1930) monographic work, redefined from a modern perspective of combined light and scanning electron ...

Classification of Microstructural Image Using a Transfer Learning Approach

2021
Mechanical properties and corrosion resistance of metal largely depend on the solidification of microstructure. Microstructure of metallic alloy is described by the grain size, type of phases, structure, shape, etc. Material characterization is an important issue in material science. A large number of attempts was made for automatic characterization of

Classification and quantification of microstructures in steels

Materials Science and Technology, 2004
AbstractThe International Institute of Welding (IIW) microstructure classification scheme for ferrous weld metals has been investigated as a basis for the quantification of complex microstructures in steels. The aim has been to cover the full range of microstructures observed in plain carbon and low alloy steel products, as well as ferritic weld metals

Effect of fly ash microsphere on the rheology and microstructure of alkali-activated fly ash/slag pastes

Cement and Concrete Research, 2018
The highly viscous property of alkali silicate-activated cements is one of the critical challenges that hinder their wide application. The present study focuses on ameliorating the rheological performance of sodium silicate-activated fly ash/slag pastes ...

Internal Microstructure Dictates Yielding and Flow of Jammed Suspensions and Emulsions.

ACS Nano
We propose a microstructural classification of jammed suspensions made of soft, deformable colloids with purely repulsive interactions. Three distinct classes of particles are identified, depending on their ability to accommodate topological constraints ...

Automatic Classification of Microstructures in Thermal Barrier Coating Images

2017 IEEE International Symposium on Multimedia (ISM), 2017
Thermal plasma spraying is an important manufacturing technique that creates a thermal barrier coating to protect the surface underneath from wear, erosion, oxidation and corrosion. In this paper, we develop a new microstructure classification and quantification (MCQ) module that could fully automatically classify and quantify two types of ...

Classification of microstructural changes in laser hardened steel surfaces

Materials Science and Engineering A, 2003
Three different steels with C contents of ∼0.2 wt.% and different contents of chromium, molybdenum and vanadium were similarly laser hardened after different preceding heat treatments. The laser-affected zones beneath the surface were characterised by microhardness, dislocation density, carbide type, size and distribution as well as grain size of the ...
