AbstractNon weldable Ni-based superalloys are susceptible to cracking during their elaboration by additive manufacturing (solidification cracking) or during subsequent heat treatments (strain-age cracking). This proposed study aims at investigating the relationship between the microstructure and these cracking phenomena.
ProfileEngineer and / or Master of Science - Good level of general and scientific culture. Good level of knowledge of French (B2 level in french is required) and English. (B2 level in english is required) Good analytical, synthesis, innovation and communication skills. Qualities of adaptability and creativity. Teaching skills. Motivation for research activity. Coherent professional project.

Prerequisite (specific skills for this thesis):
The candidate should have a strong appetance for experimental result-based research. Good knowledge of nickel based superalloys metallurgy and solidification mechanisms, as well as a first experience in microstructural characterizations, would be appreciated.

Applicants should supply the following :
• a detailed resume
• a copy of the identity card or passport
• a covering letter explaining the applicant’s motivation for the position
• detailed exam results
• two references : the name and contact details of at least two people who could be contacted
• to provide an appreciation of the candidate
• Your notes of M1, M2
• level of English equivalent TOEIC
to be sent to
