This is a collection of manuscripts presented at the 2nd International Congress on 3D MaterialsScience, a conference organized by The Minerals, Metals & Materials Society (TMS), the AdvancedCharacterization, Testing and Simulation Committee, and the six congress organizers, and held inAnnecy, France, on June 29–July 2, 2014.Building on the great success of the first event in 2012, the 2nd Congress on 3D Materials Scienceconvened researchers and engineers to assess the state-of-the-art in 3D materials science anddetermine paths to further the global advancement of this field. More than 150 presenters andattendees from all over the world contributed to this congress in the form of presentations, livelydiscussions, and manuscripts presented in this volume. The international advisory committeemembers, representing 11 different countries, actively participated in selecting the contributions,reviewing the manuscripts, and promoting the congress.The congress consisted of 2 keynote presentations from international experts, 96 contributedpresentations (in two parallel sessions), 75 poster presentations, and 1 panel discussion. From theposter sessions, outstanding posters were selected for awards, which were presented to the authorsat the congress dinner. The event concluded with a closing panel of experts focusing the discussionon the evolution of 3D materials science in the period between the two congresses and the futuredirections.The 20 papers presented in this proceedings publication are divided into 6 sections: (1) Acquisitionand Handling of 3D Data; (2) Microstructure/Property Relationship in 3D: Characterization andSimulation; (3) Microstructure/Property Relationship in 3D: Deformation and Damage; (4) NewExperimental Techniques; (5) Analysis at the Nanoscale; (6) Dynamic Processes. It is our hopethat the 2nd International Congress on 3D Materials Science and these proceedings will furtherthe implementation of three-dimensional materials science and broaden its variety of applications.< Réduire
