Austenite Evolution and Solute Partitioning during Thermal Cycling in the Intercritical Range of a Medium-Mn Steel

Tzini M.-I., Sarafoglou P., Stieben A., Haidemenopoulos G., Bleck W. (2016)

The evolution of austenite fraction and the associated solute partitioning during the intercritical annealing of medium-Mn steels are of great importance for austenite stabilization and the mechanical performance of this ...

Coupled FEA Model with Continuum Damage Mechanics for the Degradation of Polymer-based coatings on Drug-Eluting Stents

Drakoulas G., Kokkinos C., Fotiadis D., Kokkinos S., Loukas K., Moulas A.N., Semertzioglou A. (2021)

Drug-Eluting Stents (DES) are commonly used in Coronary angioplasty procedures to reduce the phenomenon of restenosis. Numerical simulations are proven to be a useful tool to the Bioengineering community in computing the ...

Fatigue and fracture behavior of pearlitic Grade 900A steel used in railway applications

Christodoulou P.I., Kermanidis A.T., Haidemenopoulos G.N. (2016)

In overloaded railway networks, rail surface defects developed under rolling contact fatigue (RCF) if left untreated, may propagate to the bulk of the rail and become critical for its structural integrity. To avoid critical ...

Mechanical performance of laser spot-welded joints in Al-Al/Cu solar thermal absorbers

Kermanidis A.T., Christodoulou P.I., Hontzopoulos E., Haidemenopoulos G.N., Kamoutsi H., Zervaki A.D. (2018)

The mechanical performance of laser spot welded joints used in Al-Cu and Al-Al thermal absorber systems has been evaluated under different laser welding and mechanical loading conditions. In the experimental investigation, ...
