TL;DR: In this paper, X-ray diffraction and atom-force microscopy were applied to characterize the structure and surface morphology of the deposited ZnO films, which were characterized by photoluminescence with an Ar ion laser as a light source.

TL;DR: In this paper, the effects of aged treatment on the microstructure and microhardness of the surface coating were studied, and the results showed that the prime phase (Co dendrite) and other phases, including Cr 23 C 6, Co 7 W 6, and CrNi existed in the coatings.
Abstract: Co-based alloy coating was deposited on tool steel by powder feeding laser cladding. Sections of such coatings were examined to reveal their microstructures and phases using scanning electron microscope (SEM) and X-ray diffractometer (XRD). The results showed that the prime phase ( γ -Co dendrite) and other phases, including Cr 23 C 6 , Co 7 W 6 , and CrNi existed in the coatings. Some different solidification morphologies, such as planar (at the interface), cellular and dendrite formed, varying from the interface to the surface. Fine microstructures of γ -Co dendrite and lamellar eutectic in dendritical regions strengthened the coatings. Besides, the effects of aged treatment on the microstructure and microhardness of the surface coating were studied. Aged treatment led to the precipitations of some carbide particles (Cr 7 C 3 and Co 3 C) and boride particles (Co 4 B) from the cladded coating, causing an increase in microhardness in the laser-cladded coating.

TL;DR: In this article, the effect of the processing variables on the lattice parameter and composition of the powder mixtures was examined and the results showed that lattice parameters of TiC x increase with the increase of C/Ti ratio.
Abstract: TiC x has been formed by self-propagating high-temperature synthesis (SHS) from elemental powder mixtures with a range of C/Ti ratios. The combusting behavior of the powder mixtures was investigated. The effect of the processing variables on the lattice parameter and the composition of TiC were examined. The results show that lattice parameters of TiC x increase with the increase of C/Ti ratio. The variation of Gibbs free energy in Al-Ti-C system was studied based on the thermodynamics theory. The results show that TiC and Al 3 Ti phases are easier to form than Al 4 C 3 phase.

24 Nov 2011TL;DR: In this paper, the authors present the complete fundamentals of multiscale modeling for graduate students and researchers in physics, materials science, chemistry, and engineering, with examples drawn from modern research on the thermodynamic properties of crystalline solids.
Abstract: Material properties emerge from phenomena on scales ranging from Angstroms to millimeters, and only a multiscale treatment can provide a complete understanding. Materials researchers must therefore understand fundamental concepts and techniques from different fields, and these are presented in a comprehensive and integrated fashion for the first time in this book. Incorporating continuum mechanics, quantum mechanics, statistical mechanics, atomistic simulations and multiscale techniques, the book explains many of the key theoretical ideas behind multiscale modeling. Classical topics are blended with new techniques to demonstrate the connections between different fields and highlight current research trends. Example applications drawn from modern research on the thermo-mechanical properties of crystalline solids are used as a unifying focus throughout the text. Together with its companion book, Continuum Mechanics and Thermodynamics (Cambridge University Press, 2011), this work presents the complete fundamentals of materials modeling for graduate students and researchers in physics, materials science, chemistry and engineering.
