Dr. Jonathan Cormier from Institut Pprime Visits IMR


The recipient of 2019 Lee Hsun Lecture Series—Lee Hsun Young Scientist Award, Dr. Jonathan Cormier from Institut Pprime visited Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS) from February 25 to March 1, 2024.

During the visit, Dr. Jonathan Cormier delivered a lecture entitled “Damage mechanisms and durability in very high cycle fatigue of Ni-based SX superalloys”. In his lecture, he reviewed failure mechanisms in fully-reversed conditions and under positive stress ratio at high temperature and discussed the question of the fatigue limit in excess of 10^10 cycles. He also proposed some perspectives regarding the impact of environment/improved processing routes and stress concentrations.

Dr. Jonathan Cormier got PhD grant from the French Ministry of Armies under the supervision of Dr. José Mendez and Dr. Xavier Milhet in 2006 and cooperated with SAFRAN Helicopter Engines. He is presently working on the kinetics of microstructure evolutions and their impact on the mechanical behavior and durability of Ni-based superalloys. He is the associate professor at ISAE-ENSMA since 2007. He won the FEMS Lecturer Award for Excellence in Materials Science and Engineering 2016-2017, FEMS-TMS International scholar award 2018, the TMS/AIME Champion Mathewson Award in 2019. He is the editor of Metallurgical and Materials Transactions A journal since Sept. 2016. He is also the member of the Program committee of 14th International Symposium on Superalloys/Superalloys 2020 (moved to 2021) and chairman of the 15th International Symposium on Superalloys/Superalloys 2024.
