Investigation of the dynamic strain aging effect in austenitic weld metals by 3D-DIC Universiteit Gent
Austenitic stainless steels similar to type AISI 316L are widely used structural materials in current and future nuclear reactors. Careful development and characterization of these materials and their welds is needed to verify the structural integrity of large-scale multicomponent structures. Understanding the local deformation behavior in heterogeneous materials and the mechanisms involved is key to further improve the performance and ...
Confirming debonding of non-metallic inclusions as an important factor in damage initiation in bearing steel Universiteit Gent
Damage in bearings is closely associated with the presence of microstructural alterations, known as white etching areas (WEAs) and white etching cracks (WECs). One of the main reasons for the creation of these microstructural alterations is the presence of defects in the material, such as non-metallic inclusions. Manganese sulfides and aluminum oxides are widely reported in the literature as the most common types of non-metallic inclusions found ...
The effect of Nb on the hydrogen embrittlement susceptibility of Q&P steel under static and dynamic loading Universiteit Gent
Evaluation of butterfly wing formation in bearing steel : the role of non-metallic inclusions and hydrogen Universiteit Gent
The effect of Nb on the strain rate and temperature dependent behaviour of quenching & partitioning steels Universiteit Gent
In present study, the potential of Niobium (Nb) to improve the mechanical properties of Quenched and Partitioning (Q&P) steels is investigated. To this purpose, the effect of the addition of Nb on the microstructure and mechanical properties of a Q&P steel was thoroughly analysed with special attention on the thermal stability of the retained austenite. The mechanical properties of the Nb Q&P steel were determined using static and ...
Microstructural investigation and identification of intermetallic σ-phase in solution annealed 316L-type austenitic stainless steel Universiteit Gent
Splitting susceptibility in modern X80 pipeline steels Universiteit Gent
The microstructure and crystallographic texture of modern industrially produced API X80 grade pipeline steels were studied to identify the factors associated with the phenomenon known as splitting, which can occur on the fracture surfaces of Charpy, drop-weight tear test and full-scale fracture propagation tests. The steels investigated originated from full-scale production of line pipes, which had shown different levels of crack arrestability ...
