About this position

This PhD position at the Slovak University of Agriculture in Nitra focuses on the effect of hydrogen on the deformation behavior and fracture of high-strength wrought complex concentrated alloys (CCAs). The research aims to deepen understanding of how hydrogen influences the mechanical properties and fracture mechanisms of advanced alloys, particularly those based on CoCrFeNi with additions such as Al, Ti, Ta, or Nb.

The successful candidate will engage in a combination of experimental and computational work. Key activities include forming, heat treatment, hydrogenation, and characterization of new CCAs. The student will investigate the relationship between hydrogen content, microstructure, and fracture toughness, employing both destructive (bending) and non-destructive (acoustic emission) testing methods. Numerical modeling of crack initiation and propagation will be performed using the finite element method (Ansys software), with results validated against experimental data from mechanical tests.

The project is supervised by Ing. Michaela Štamborská, PhD, and is based at the Institute of Materials and Machine Mechanics, Slovak Academy of Sciences, in collaboration with the Slovak University of Agriculture in Nitra. The position offers a stimulating research environment with access to advanced facilities and interdisciplinary collaboration opportunities.

Applicants should have a Master's degree in engineering or a related field, with strong experimental skills, knowledge of applied mechanics, materials science, mechanical testing, and numerical methods. Good proficiency in English and Slovak is required.

The application deadline is 31 May 2026, with the position starting on 1 September 2026. For further details and to apply, visit the university's doctoral studies portal. Administrative contact: [email protected].
