Microwave Assisted Reactive Sintering of Zirconium Oxynitrides

Metallography of Aluminium alloys

This lecture aims at providing a survey of the metallographic techniques available for the examination of aluminium and its alloys. The information must be sufficient to be sure that the students and the users are able to choose the most suitable technique to solve their problems in the examination of samples. The lecture should contain a direct understanding of the main problems in the metallo...

Special Issue on System Dynamics and Other Simulation-Based Approaches for Information Systems

This special issue of the International Journal of Information Technologies and Systems Approach (IJITSA) aims to help decision-makers understand and anticipate opportunities to deploy information systems (IS) and add business value for organizations in today’s competitive environment. Enhancing the knowledge of gaining business value from IS is possible by achieving insights into the complex b...

Reduced yield stress for zirconium exposed to iodine: reactive force field simulation

Iodine-induced stress-corrosion cracking (ISCC), a known failure mode for nuclear fuel cladding, occurs when iodine generated during the irradiation of a nuclear fuel pellet escapes the pellet through diffusion or thermal cracking and chemically interacts with the inner surface of the clad material, inducing a subsequent effect on the cladding’s resistance to mechanical stress. To complement ex...
