AbstractThis research project aims at better understanding the links between intermediate-level segregations (so-called mesosegregations) and mechanical properties (in particular, fracture properties) of steels used in heavy components fabricated from ingots. A quantitative microstructural characterization method will be set up and used for various segregation intensities. A mechanical characterization method will also be developed. These experimental results will be capitalized in a model, involving the local approach to fracture. The model will allow predicting properties of materials containing such segregations.
ProfileTo be admitted to a doctorate, the candidate must hold a national master's degree or another diploma conferring the master's degree (engineering diploma, equivalent foreign diploma, etc.), following a course of training establishing his research aptitude.
Applicants will be selected after interview before a jury assessing their research aptitude and the adequacy of their training and knowledge with the proposed thesis subject. Strong scientific knowledge, a first research experience (internship 4 months minimum), a strong motivation for research, a good level in English will be required (minimum B2).
The application must include:
a motivation letter including the candidate's professional project
a detailed curriculum vitae mentioning studies, research internships carried out, diplomas with date obtained, professional experience, research axes envisaged
a transcript of marks from the previous course (engineer and / or master cycle)
one or more letters of recommendation ...
a certificate of English level.
for a non-French speaking student, an A2 / B1 level in French (European standard) is recommended when entering a doctorate
for students who do not hold a national research masters diploma, all documents attesting to the students qualifications in research training (research internship certificates with summary of the dissertation, recommendations, publications, etc.)
a copy of identity card or passport

The documents in pdf format must be sent to no later than June 8
