Crousen, Leon (author)A long standing research field in material science has been the trade-off between strength and ductility of steels. Advanced High Strength Steels (AHSS) aim to combine these two properties and provide steels that can increase safety and lower CO2 consumption in automotive applications, by decreasing weight. To further decrease the environmental...master thesis 2021

Chou, Chan Hung (author)Laser surface treatment shows great potential to locally create distinct phases in martensitic steels due to its highly localized laser heat flux. Architectured materials with microstructures of metastable austenite/martensite phases exhibit advanced mechanical properties, such as a better combination of strength and ductility. In addition, the...master thesis 2021

Kong, Winnie (author)Many manufacturing industries have been impacted by the innovation of additive manufacturing (AM), and biomaterials manufacturing is no exception. One group of biomaterials impacted by the innovation of 3D printing are degradable biomaterials. Degradable biomaterials could eliminate the need for surgery to remove the implant. 3D printed porous...master thesis 2021

Kosari, A. (author)For many decades, corrosion and corrosion inhibition of high-strength aluminium alloys have been studied indirectly and through traditional and separately performed electrochemical, spectroscopic and microscopic techniques. These approaches employed to date commonly lack sufficient lateral and time resolution to unravel early-stage events which...doctoral thesis 2021

Bischoff Tulleken, Ben (author)Corrosion and fouling are considered major factors affecting the performance of water-steam cycles (WSC). Flow-accelerated corrosion (FAC), present in feed and condensate systems, is a well known corrosion mechanism, eroding and dissolving the protective magnetite layers. Fouling of the boiler, by suspended magnetite particles, is partly...master thesis 2021

Influence of different corrosion solutions on reinforced concrete by DIC and traditional strain testWang, XiaoX (author), Liu, JiaP (author), Zhong, PeiH (author)When the corrosion expansion stress of the steel reinforcement exceeds the ultimate tensile strength of the concrete, the concrete will crack and eventually cause structural damage. Therefore, direct characterization methods of steel corrosion expansion stress can help predict the concrete cracking time, prevent corrosion expansion and repair...conference paper 2021

Wang, Tiao (author), Luan, Yao (author)Reinforcement corrosion induced by chloride ingress is one of the major threats of reinforced concrete (RC) structures exposed to chloride attack. The cracks of concrete cover provide additional paths of chloride ingress and facilitate the reinforcement corrosion. Current information regarding the influence of crack development on corrosion...conference paper 2021

GevaudanE, Juan Pablo (author), Bernal, Susan A. (author)The aim of this study is to understand the corrosion mechanism of steel embedded in alkali-activated slag/metakaolin blended concretes via electrochemical testing after 407 days of exposure to a 3.5 wt.% NaCl solution, with an emphasis on characterising the material prior to the onset of corrosion. In order to accurately depict the material’s...conference paper 2021

Zhang, Zhidong (author), Angst, Ueli M. (author)The structure of concrete, in particular the microstructure of the steel-concrete interface (SCI), can significantly affect corrosion of rebars. To support corrosion, oxygen needs to diffuse from the ambient environment to the steel surface. Meanwhile, corrosion products transport through the SCI and precipitate in concrete. Transport properties...conference paper 2021

Chen, Zhipei (author)Currents flowing along paths not being elements of a purpose-built electric circuit, are called stray currents. Various types of reinforced concrete structures (such as viaducts, bridges and tunnels) in the neighborhoods of railways may be subjected to stray current leaking from the rails. In these cases the concrete pore solution acts as an...doctoral thesis 2021

Eivani, A.R. (author), Mehdizade, M. (author), Chabok, S. (author), Zhou, J. (author)Magnesium alloys have many unique properties, mostly benefitting from the low density of magnesium. However, they are not competitive, when compared with other lightweight materials, such as aluminum alloys, particularly in ductility and corrosion resistance. There is a strong need to improve the mechanical properties and corrosion resistance...journal article 2021
