PostDoc Scientist at the European XFEL (2022-2025)


Doriana has a MSc. in Chemistry and a PhD Europaeus in Geosciences. She has ~7 years of experience in X-ray crystallography. Since April 2020, she is postdoc researcher at the PIMM lab (CNRS) where she does research in Materials Science (microstructure analysis of metals by means of time resolved X-ray diffraction). Currently, she is PostDoc Scientist at the Femtosecond X-ray Experiment beamline at the European X-ray Free Electrons Laser.

Research Project:


DIFFABS beamline of SOLEIL Synchrotron (Ultrasonic fatigue machine on the 6-circles diffractometer)Several mechanical structures are subjected to repeated loadings during their lifespan and can break under stress lower than the ultimate tensile stress. This phenomenon, called fatigue of materials, has attracted the scientific community attention as several fractures occurring in many industrial sectors are due to fatigue. Therefore, it is important to characterize the fatigue life to ensure the safety and reliability of mechanical structures throughout their life service. Fatigue characterization requires tests during which the material is cyclically loaded at different stress until its fracture (S-N curves). However, it is common to find mechanical systems subjected to several billion cycles, in what is called the very high cycle fatigue (VHCF) domain [1]. Their fatigue characterization with conventional hydraulic fatigue machines, operating typically at 100Hz, requires excessive testing time (e.g. three years are necessary to reach 109 cycles). In order to reduce this limiting time, new approaches using ultrasonic fatigue machines operating between 20 and 30 kHz have been developed during the last decades[2-4]. Fatigue life is influenced by several factors, such as microstructure and residual stresses. It is well-know that X-ray diffraction analysis is a powerful tool to study the microstructure of a material (particularly a metal in this case) as the shift of the X-ray diffraction peak position provides the mean elastic lattice strain at the scale of the diffracting volume, and the line-broadening provides the elastic lattice strain heterogeneity. However, in X-ray diffraction studies on polycrystalline samples, the elastic line-broadening anisotropy did not receive so much attention. Therefore, the aim of my work is to show how it is possible to in-situ investigate the microstructure and residual stress of poly(mono)crystalline materials during ultrasonic fatigue test in VHCF domain by interpreting the X-ray line-broadening with a micromechanical model accounting for the specimen microstructure and residual stress.
