Guillaume Hachet

Dr. Guillaume Hachet is a Researcher at the Max Planck Institute for Sustainable Materials, affiliated with the Department of Microstructure Physics and Alloy Design. His work focuses on mechanism-based alloy design, particularly investigating interactions between hydrogen, dislocations, and microstructural evolution in advanced materials. He holds a PhD in Materials Science and has conducted extensive research on metallurgical processes and defect mechanics.

Key research interests include hydrogen embrittlement mechanisms in alloys, dislocation dynamics in metals like tungsten and nickel, and the impact of interstitial elements on mechanical properties. His experimental methods involve atom probe tomography, nanoindentation, and ab initio simulations. Dr. Hachet’s studies often bridge multi-scale analysis from atomic-level defects to macroscopic material behavior.

Recent publications emphasize hydrogen’s role in delaying precipitation processes, altering dislocation mobility, and modifying cyclic plasticity in single crystals. His work contributes to improving alloy design for applications in harsh environments such as nuclear reactors and aerospace components. Dr. Hachet collaborates with the Mechanism-based Alloy Design research group at the institute and maintains an active presence in the materials science community through conferences and interdisciplinary projects.
