Pablo started his Ph.D studies on September 2015 at Ruhr-Universität Bochum, Germany. He works on the study of the mechanical properties and phase stability of High-Entropy (HE) alloys. HE alloys were defined as equiatomic or near-equiatomic alloys containing at least five principal elements. The most studied HE alloy is the CrNiCoFeNi system, which present excellent mechanical and fracture properties and good corrosion resistance. On this context, it is important to understand the roll of main components (Cr, Ni and Co) of HE alloys, and to study the phase stability by means of the binary, ternary and finally quaternary systems.

Joaquín started his Ph.D studies on August 2016 at Universität der Bundeswehr, Germany. The main purpose of his work is the study of shape and density variation of the parts or pieces by AM, accordingly to the applied mechanical solicitation, throughout Finite Element Method (FEM) analysis. The work will aim at the development of new structures that can be achieved with new AM technologies, such as selective laser sintering, electron beam melting, VAT photopolymerisation and the well known material jetting (commercial 3D printers). The obtaining of mentioned structures involve product improvement technics, related to computational mechanics field. It will be applied topology optimization tasks to minimize different parameters like strain energy, effective stresses or stress intensity factors using the volume or density as a constraint. The new developed structures will be tested by mechanical-structural analysis and evaluated to be manufactured by AM.

Yenny started her Ph.D studies on August 2016 at Texas A&M University, United States of America. She earned her B.S. degree in Chemical Engineering from the National University of Colombia in 2013 investigating the effect of imidazoline-based corrosion inhibitors on mild steel in a carbon dioxide environment. She carried out this investigation at the University of Akron, Ohio, enrolled in an undergraduate research assistant program. She was accepted in the Department of Materials Science and Engineering at Texas A&M University in Spring 2015. Currently, She is studying the corrosion protection by hybrid inorganic/organic coatings and expect graduating from my Master's Degree in summer 2016 investigating the performance of Zn-rich epoxy coatings containing carbon nanotubes on the corrosion protection of carbon steel substrates. She is pursuing a PhD in the Department of Materials Science and Engineering at Texas A&M University starting in Fall 2016. My research interests are focused on mechanisms of corrosion, corrosion protection and control, advanced electrochemical characterization, and nanotechnology-based coatings.

Fernando started his Ph.D studies on January 2016 at University of Cambridge. The main purpose of his work consists in the construction and implementation of physics-based models of behaviour that can accurately estimate the mechanical properties of nickel-based superalloys depending on their microstructure and composition. More specifically, the modelling work focuses on the different phenomena that take place during high cycle fatigue. These materials are currently used in components that need to operate at high temperatures and under considerable stresses, such as turbine discs and blades. Thus, the importance of the project relies on the direct benefits that can be obtained in industry from both, a deep understanding of the existing deformation and crack nucleation mechanisms that occur during cyclic loading, and the ability to predict the influence that different microstructural parameters may have on the final performance of the component. Additionally, the capacity to accurately predict these properties would also be an important tool for designing alloys with better mechanical properties.

Jeanette started her Ph.D studies on October 2014 at The University of Manchester. The main purpose of her work is focus on hard anodic films for aluminium alloys. Anodizing treatments are used for protection of aluminium alloys against wear and corrosion in aerospace, architectural and other sectors of industry. The treatments involve polarizing an alloy in an acid electrolyte to produce a nanoporous anodic film composed of alumina. Hard anodic films are generated by so-called hard anodizing, which often involves growth of the film at high currents in an electrolyte at low temperature. The resultant coatings reveal a cellular morphology, with cylindrical nanopores orientated normal to the film surface that run through most of the film thickness. The objective of the project is to investigate the mechanism of formation of hard anodic alumina films on aluminium and AA2024-T3 alloy, which differs from the mechanism of conventional anodizing. For this purpose, a variety of experimental methods are being employed to probe the films at resolution from micro to nanoscale.
