Modern scientific research is highly specialised and concentrated on specific aspects of the scientist’s scientific field. However, when complex challenges arise, such as the sustainable energy transition, strong collaboration between scientific fields is required. Unfortunately, in many cases, these fields do not overlap, which causes...

Organ-on-chip (OoC) is invented around 10 years ago which is used to do pre-clinical drug test without live animals. Physiological microenvironment of different cells can be mimicked in OoC. In order to better form of tissue in OoC, mechanical stimulation can offer through different ways including pneumatic, thermal, and electric stimulations....

In our modern world, where computers, mobile phones and many other applications have become indispensable, there is a growing need for high precision machines in order to be able to produce these technologies. For these complex high precision applications it is important to understand the fatigue properties of the materials used to prevent...

Plasticity accompanied by dislocation motion is the essential property of metals. A large number of crystal plasticity models have been developed to predict the mechanical response in the work hardening regime while little attention is paid to pre-yield behavior. In this work, we propose a novel model both pre-yield and post-yield from a...

Essential criteria to a shaving blade include wear resistance, corrosion resistance and a sharp cutting edge. The material selection for improved cutting elements as well as increasing the longevity of the blade would provide benefits not only to the consumer experience of a more efficient shaving performance, but also a more sustainable...

Carburized steel grades are widely used in applications where high hardness at the surface is required in combination with good core toughness as well as high fatigue resistance. The process of carburizing lower to medium carbon steel can generally provide this combination of properties and has been practised for several decades. Such steel is...

Cyclic grinding maintenance of rails removes surface degradations and damages and restores the original rail profile, which deteriorated during wheel-rail contacts. Thus, cyclic grinding increases the service life of a rail and prevents catastrophic rail failure. Besides the advantages of cyclic grinding, concerns have risen that grinding itself...

In the framework of the High Luminosity LHC project at CERN, the need for further incorporation of evaluation of radiation damage into the design of beam intercepting devices at CERN is described and the risks of radiation damage in high energy applications are summarized. Radiation damage can be an important topic in high energy applications...

In recent years, the concept of high entropy alloys (HEAs) has gained increasing attention due to their unique compositions, microstructures and properties. High entropy alloys are defined as solid-solution alloys with 5 or more principal elements in equal or nearly equal atomic fractions with the elemental concentrations ranging from 5 – 35at%....

Interstitial free (IF) steel is widely used in the automobile industry for car outer panel because of its good formability. Recently automotive industry pays more attention to paint appearance, and therefore demands good waviness performance of sheet steels after stamping. This thesis aims to study the factors in the microstructure that...

With a combination of high strength and good formability, dual-phase steels have gained much interest in the automobile industry. The final microstructure, which leads to mechanical properties of the product, is strongly dependent on the processing of the steel. Apart from hot-rolling and cold-rolling, the parameters during continuous annealing...

The mechanical properties of steel are influenced by its microstructure, which is obtained as a result of processing conditions. It is, thus, important to study the effect of these conditions on the microstructure. A three dimensional microstructure model, based on a cellular automata (CA) model, was previously developed. The model is capable of...

Samples from two bronze Geistingen axes, one from Nijmegen and one from Tongeren, are examined and analysed in order to answer the question ‘How are they produced?’. It is concluded that both axes do not have the same composition: the Nijmegen axe is identified as a binary copper-tin bronze, while the Tongeren axe is regarded as a ternary copper...
