Defect and Diffusion Forum

Description:

Defects and diffusion are key concepts at the description of nuclear materials behavior at thermal and radiation impacts. The evolution of various defects (such as point defects, dislocations, grain boundaries) determines changes of the materials properties under operating conditions. The present issue contains new and relevant data about the diffusion and defects in nuclear fuel (uranium alloys, oxide and nitride fuel) and structural materials (steel and non-ferrous metals). We hope that this special issue will be useful for researchers and engineers working in the field of material science and nuclear engineering. We wish to thank the authors for their contributions to this special issue and reviewers for their cooperation and efforts to prepare and evaluate the manuscripts.

Description: The special issue “Transfer Phenomena in Fluid and Heat Flows III” of the journal “Defect and Diffusion Forum” presents papers covering theoretical and practical aspects of modeling and numerical investigation of the diffusive convection, magnetohydromagnetic mixed convective flows and heat transfer phenomena in different media and engineering objects.
We hope that our special issue will be very interesting and useful for a wide audience of researchers and engineers from various fields of human activity.

Description: Some theoretical aspects, practical results and experimental techniques of use of the positron annihilation phenomena in the research of the structure, defects of structure and other properties of different materials and mediums are covered in this journal volume. It comprises the papers presented at the 17th International Conference on Positron Annihilation (ICPA-17, Wuhan, China, 20-25 September, 2015).

Description: The special volume of the Defect and Diffusion Forum periodical, which is titled “Transfer Phenomena in Fluid and Heat Flows”, covers a variety of interesting topics related to diffusion phenomena, heat transfer, and fluid flows.

Description: The topical volume “Recent Developments in Mass Transport and Related Phenomena in Materials” is intended to capture a broad cross-section of contemporary research on mass transport and related phenomena in a wide spectrum of technologically important materials. The range of topics presented in this volume is very wide, covering theory, computer simulations and experiments dealing with a wide variety of materials. This reflects the enormous breadth of this area.

Description: This special topic volume  of Defect and Diffusion Forum covers in a wider sense diffusion related phenomena. One of the most important challenges of modern society is the efficient, secure and sustainable generation and conversion of energy. This topics spans from the application of classical fossil fuels (e.g. oil and coal based) to natural gas and more alternative approaches which are based on bio fuels, solar energy and wave energy conversion. In the same way important are the connected topics of reusing waste thermal energy as well as the opposite need of cooling. A further topic which requires a similar skill set and which is covered in this topical volume is related to the manufacturing (e.g. furnaces), modification (e.g. heat treatment) and processing (thermal cutting) of materials.

Description: This special issue of Defect and Diffusion Forum contains selected peer-reviewed papers presented at the eleventh International Conference on Diffusion in Solids and Liquids (DSL-2015) held at the NH München Messe, Germany during the period 22nd-26th June, 2015. The goal of the conference was to provide a unique opportunity to exchange information, to present the latest results on material engineering, material defects analysis, and diffusion processes.

Description:

The present collection of papers from 12^th International Conference „Local Mechanical Properties“ which was held on November 04.- 06.2015 in Liberec, Czech Republic presents current publications of conference participants from several countries .

Besides the traditional research in area of mechanical properties of different metallic materials, composites, polymers was focused attention also on research of thin layers and nanomaterials. The significant potential of application of these new materials significantly affects on research activities of academia. Future application of innovative materials in different areas of human activities, already requires from researchers the definition of materials properties on atomic level. Conference by its content contributed to the deepening of knowledge about the internal structure of various materials, their mechanical and tribological properties.

Description: Present issue is devoted to problems classical mass diffusion such as phase transformations, corrosion behavior, coatings and microstructures and extensions to new research in the field of nanotechnology. Were investigated classical carbon and alloy steels, titanium and aluminum alloys as well as polymer materials. Technical applications relate to oil recovery, surface quality, and improved material properties for machining and processing. Many of these topics are related to experimental measurements and methods as well as numerical simulation and approaches to predict properties and processes.

Description: In this issue are published results of high-tech application of computational modeling and simulation the dynamics of different flows, heat and mass transfer in different fields of science and engineering.
