Sinter is a blast furnace input material obtained by heating to 900-1200 oC without full melting and adhering each other with superficial melting. It considered as multi-phase its sinter heterogeneous microstructure. In general, the main mineral phases are hematite, magnetite, silicoferrite of calcium aluminium (SFCA) silicates. By determining SFCA structure in material, sintering process will ...

Near-net shape processes, such as laser metal deposition (LMD), offer a unique combination of process flexibility, time savings, and reduced cost in producing titanium alloy components. The current challenge in processing titanium alloys using LMD methods is understanding the complex microstructural evolution as a part is fabricated layer by layer. The microstructure is affected by the repeated...

The exploration of new alloys with desirable properties has been a long-standing challenge in materials science because of the complex relationship between composition and microstructure. In this Research Article, we demonstrate a combinatorial strategy for the exploration of composition dependence of microstructure. This strategy is comprised of alloy library synthesis followed by high-through...

in industrial applications, most materials are exposed to wear and friction because multiple conditions are used. however, the tribological properties of these materials can be improved with different techniques. one such technique that improves the frictional property of a surface is the use of self-lubricating coatings. in this study, multicomponent coatings of nominal composition cu-ni3al-mo...

Substantial in-plane crystallinity and dominant face-on stacking are observed in thin films of a high-mobility n-type rylene-thiophene copolymer. Spun films of the polymer, previously thought to have little or no order are found to exhibit an ordered microstructure at both interfaces, and in the bulk. The implications of this type of packing and crystalline morphology are discussed as they rela...

This paper described the development of chitosan composites containing precipitated hydroxyapatite particles for potential applications in orthopaedic surgery or waste water treatment. The synthetic process and morphology of hydroxyapatite were reported. The effects of hydroxyapatite content on the microstructure and mechanical properties of composites were investigated. It was found that the Y...

In this report, a technique for rapid synthesis of ZnO microstructures by microwave-assisted heating of precursors at hydrothermal conditions is demonstrated. Further, the reaction mechanism for the growth of ZnO microstructures is analyzed. An accelerated rate of reaction obtained using microwaves enables a dissolution-recrystallization mechanism for generation of one dimensional (1D) rod-like...

Four-dimensional propagation-based phase contrast X-ray tomographic microscopy experiments were performed on an Aluminum29.9mass% Silicon alloy during coarsening. Using propagation-based phase contrast, changes in the three-dimensional morphology of primary silicon particles were captured and the resulting evolution of the microstructure is discussed. While morphologies at earlier times are com...
