Context & Job description
Thesis subject: In-situ cryogenic mechanical testing by neutron diffraction for ultra-low-temperature applications
You will be supervised by Dr Sandra Cabeza within the SALSA’s strain diffractometer team at the ILL, Grenoble, France. SALSA is a diffractometer which enables the measurement of internal strain (residual and applied) in engineering materials, specialised for spatial- and temporal-resolved investigations and optimized for in-situ and operando characterization.
You will be co-supervised by Prof. Dr.-Ing Wolfram Volk at the chair of metal forming and casting at Technical University of Munich (TUM). The Chair is specialized in the areas of material characterisation for metals, forming processes (such as deep drawing and shear-cutting) and metal casting. The chair offers access to industry grade forming and shear-cutting presses, as well as to an well equipped workshop for classical material characterisation, such as tensile test and other sheet metal testing equipement. The institute is located directly next to the FRMII neutron source, fostering collaboration with neutron science.
The aim of the PhD project is to understand the mechanical behaviour of steel and aluminium alloys at cryogenic temperatures. This projects enhances the bridging of fundamental material science to a field of high technological and societal relevance concerning the green transition (Liquid Hydrogen) and European sovereignty regarding Liquefied Natural Gas (LNG). Specimen preparation and traditional laboratory material characterisation will be conducted at the Technical University of Munich (TUM) at the Chair of Metal Forming and Casting (utg). Neutron in-situ tensile characterisations at cryogenic temperatures will be conducted at ILL-SALSA in collaboration with STFC-ENGINX and FRM II. Data analysis will allow for a correlation of the mechanical properties at different scales to determine the responsible mechanics at the atomic level of the cryogenic change in mechanical properties.
Further information may be obtained from: Dr. Sandra Cabeza (tel.: +33 (0) 457428104, email: cabeza@ill.fr), Prof. Dr.-Ing. Wolfram Volk (tel.: +49 89 289 13997, email: info@utg.de)
Expected profile
- Degree allowing enrolment for a PhD (such as MSc, Master 2 de Recherche, Laurea or equivalent) in materials science, physics, mechanical engineering, or a related discipline, with a strong focus on metallurgy and mechanical characterization. Knowledge of diffraction methods will be an advantage.
- Certain level of autonomy in experimental work considering design, data analysis and interpretation.
- Programming skills for data processing and simulation (e.g., Python, Matlab, Finite Element Modelling Software).
- Excellent communication skills.
- As an international research centre, we are particularly keen to ensure that we also attract applicants from outside France. You must have a professional knowledge of English and be willing to learn French (a language course will be paid for by the ILL). Knowledge of German would be also considered as an advantage
- Proficiency in English (A proof of upper-intermediate level must be included in the application. Applicants originating from native-English-speaking countries can apply without the need for proof of level. An official degree conducted in English will be also accepted as a proof). If the applicant is unable to provide proof, an English test (free of charge) will be requested.
- Compliance with the Marie Sklodowska-Curie mobility rule: candidates may not have resided or carried out their main activity (work, studies, etc.) in the host institute’s country for more than twelve months in the three years immediately before the application deadline.
- All researchers recruited must be doctoral candidates, i.e. not already working towards or in possession of a doctoral degree at the date of the recruitment.
- Candidates must satisfy the conditions for enrolment in a doctoral programme.
Working conditions
The successful candidate will be enrolled in the Graduate School of the School for Engineering and Design at Technical University Munich (Germany) and based with a full-time contract at the ILL (Grenoble, France). For a period of 2-3 months per year a stay at TUM will be foreseen for sample preparation and lab characterization. Additional visits may be arranged when needed. Furthermore, a varied pedagogical training programme will be offered to the successful candidate throughout the 3-year PhD project. The candidate will receive full access to the programmes offered by the TUM Graduate School.
