Abstract
Failure in structural alloys initiate through nucleation and growth of microstructural damage incidents,
such as delamination at phase boundaries, or cracking of brittle phases. Activation of these
mechanisms limit processing (e.g. formability), lifetime, and reuse potential at end-of-life. In this talk,
first, novel in-situ methods developed in Tasan Group will be presented, which help us better
understand these mechanisms. These micro-mechanical findings enable us to identify damage-resistant
microstructure / alloy design strategies, e.g. for nanolaminated steels, metastable high entropy alloys,
multi-gradient alloys, resettable microstructures, which will also be discussed in the talk.
Biography
Prof. C. Cem Tasan is an Associate Professor of Materials Science and Engineering in the Dept. of Materials Science and Engineering at MIT. He received his BSc and MSc degrees from the Metallurgical and Materials Engineering Dept. of METU, Ankara/Turkey. He then moved to Eindhoven/Netherlands, to carry out his PhD within the group of Prof. Marc Geers in the Mechanical Engineering Dept. of Eindhoven University of Technology. Following his PhD degree in 2010 and two years of post-doc with Prof. Dierk Raabe in Max-Planck Institut fur Eisenforschung (MPIE), he was appointed in MPIE as a Group Leader, leading the Adaptive Structural Materials group until joining MIT in January 2016. Prof. Tasan’s research explores the boundaries of physical metallurgy, solid mechanics, and in-situ microscopy, in order to provide metals solutions to engineering challenges. His research activities have led to 80+ journal publications, +50 invited talks in various institutions or meetings, and several awards – the most recent being the 2020 TMS Early Career Award.
