The thermal behavior of actomyosin from the porcine skeletal muscle under various heating conditions including retort processing was examined. The physical properties (breaking energy, modulus of elasticity and water release rate) of the heat-induced gels of actomyosin decreased with increasing heating temperature or heating rate. The microstructure of the gel exhibiting lower physical property...

The martensite steels produced by quenching and tempering has been used for machine structural use. Martensite in ferrite-martensite dual-phase steels (hereinafter, DP steels) also has important roll in strengthening of the automobile steel sheets. Therefore the importance of analyzing the microstructure and their mechanical properties of the martensite has been increased year by year. Many res...

The impact of the nonionic surfactant, dodecyl triethyleneglycol ether (C(12)E(3)) on the solution microstructure of the dialkyl chain cationic surfactant, dihexadecyl dimethyl ammonium bromide, (DHDAB) has been investigated. The variation in solution microstructure has been studied using a combination of small angle neutron scattering, ultra small angle neutron scattering, optical texture and ...

the study of nucleation mechanism of new grains during severe plastic deformation of magnesium alloys is of great importance to control the characteristics of final microstructures.  to investigate the role of discontinuous recrystallization, a wrought az31 magnesium alloy was deformed by accumulative back extrusion process at 330 °c.  the obtained microstructures were studied using optical and...

A selective laser melting (SLM)-based, additively-manufactured Ti-6Al-4V alloy is prone to the accumulation of undesirable defects during layer-by-layer material build-up. Defects in the form of complex-shaped pores are one of the critical issues that need to be considered during the processing of this alloy. Depending on the process parameters, pores with concave or convex boundaries may occur...

The objective of this project is the development of a multi-scale simulation tool for designing thermo-mechanical processes to achieve control of microstructure-sensitive properties in materials used in applications of interest to the U.S. Army. As a part of continuing research effort, developments in the year 2004-05 are presented. An efficient large strain homogenization tool has been develop...

In the present paper, the evolution of an oxidation process has been associated to the collective atomic arrangement, the microstructure one. This microstructural analysis encompasses a metallographic examination and a relation of electricity to chemical changes in salt-water solution. The electrochemical experimental techniques used include corrosion potential measurements. To seek a deeper un...

The cervix softens and shortens as its collagen microstructure rearranges in preparation for birth, but premature change may lead to premature birth. The global preterm birth rate has not decreased despite decades of research, likely because cervical microstructure is poorly understood. Our group has developed a multilevel approach to evaluating the human cervix. We are developing quantitative ...

Today, the characterisation of the microstructure of cement-based materials using non-destructive techniques has become an important topic of study, and among them, the impedance spectroscopy has recently experienced great progress. In this research, mortars with two different contents of fly ash were exposed to four different constant temperature and relative humidity environments during a 180...

Abstract. Suitable macroscopic quantities are identified and used to assess the field distribution within a composite specimen of finite size with random microstructure. Composites made of N anisotropic dielectric materials are considered. The characteristic length scale of the microstructure relative to the length scale of the specimen is denoted by ε and realizations of the random composite m...
