De Krijger, J. (author)
Meta-biomaterials are porous biomaterials created by additive manufacturing techniques such as Selective Laser Melting. These materials are built up form a repeating unit cell, resulting in a porous structure that can be applied for bone implants or prosthetics. The mechanical properties of these meta-biomaterials can be tailored by variations...

This Ph.D. thesis investigates the relation between microstructural and mechanical properties of Advanced High Strength Steels (AHSS), with the goal of developing a microstructure with optimised mechanical properties. Among different grades of AHSS, Quenching and Partitioning (Q&P) steel which is composed of thin films of retained austenite...

The introduction of advanced high strengths steels enabled automotive manufacturers to simultaneously reduce weight and increase safety of vehicles. However issues were reported concerning the weldability of these steels. These issues concerned both the manufacturability as well as the performance of resistance spot welded joints. The...

In this PhD work, a new surface treatment based on the application of Zr-based conversion coatings by immersion in a Cu containing Zr-based conversion solution was investigated as a replacement of the traditional phosphating process for the automotive industry. Nowadays most of the cars are made of a combination of different metals, therefore,...

To increase lifetime of the protective thermal barrier coatings (TBC) in jet engines and other gas turbines, a self-healing approach based on MoSi2 healing particle addition is considered. However, due to rapid oxygen transport in yttria-stabilized zirconia (YSZ), a common TBC material, premature oxidation is a major problem. This thesis...

Fast increasing of generation and release of undesirable pollutants by the industrialization raise concerns about the environmental consequences of waste disposal. Among these waste materials, non-recycled waste glass constitutes one of the majority wastes produced in many European countries and sets a major environmental issue. Although glass...

In this thesis the effect of single and multipass welding on the microstructure and hardness of X65 linepipe steel of four different chemical compositions was investigated. The welding was simulated for three different heat inputs and two second pass peak temperatures. The thermal simulation has been achieved by simulating the CGHAZ with a...

Lithium ion batteries have attracted a lot of attentions due to the high power density and specific density that can potentially meet the requirements of new applications in the future. In recent years, one of the most promising cathode layer applied in lithium-ion batteries is called spinel LiNi0.5Mn1.5O4 (LNMO), which has advantages of high...

Basic oxygen furnace (BOF) slag is a by-product of the steel conversion process in a basic oxygen furnace. A previous study at Tata Steel in Ijmuiden has discovered the inhibition effect of BOF-slag on the corrosion of cold rolled- and hot-dip galvanized steel. This inhibition effect and its mechanism was studied in this work and its was...

Bending of dual-phase (DP) steels has introduced new issues concerning the analysis by finite element (FE) modelling. During the investigation of the microstructure of a DP1000 steel, it is found that there is crack formation at lower bending angles and elongations than would be expected based on the forming limit curves (FLCs). The results of...

Remmerswaal, T.A.N. (author)
Modern steel alloys are composed of several phases, for example ferrite and martensite. By varying the fraction or the size of the grains of these phases, the mechanical properties of the alloy can be altered. These microstructural variations were already found before to influence the corrosion properties of the alloy; this has been investigated...

Copper-nickel alloys are used for pipe systems that come into contact with seawater. These alloys are known under the group name cunifer alloys. In this research cunifer alloy CuNi10Fe (with 10 percent nickel) was investigated. The weld filler was a cunifer alloy with 30 percent nickel (CuNi30Fe). While generally there should be little corrosion...

The drive for ever more safety and fuel efficiency in the automotive industry led the industry to search for steels with enhanced strength and ductility. Promising candidates to satisfy these demands are steels with a microstructure consisting of martensite and significant fractions of retained austenite. One class of steels with such a...

Magnesium hydride (MgH2) is a well known hydrogen storage material. It has a low weight, high abundance and low cost. It is also characterised by slow kinetics and corrosive properties. To improve this, MgH2 is ball milled (bm) to create nanoparticles and is encapsulated with sulphur (S). MgH2 samples with S are compared to samples without S....

In this rapidly evolving industry, welding is the most important way to join the metals and other materials to each other. As an example, offshore pipe laying is one of the most applicable areas for welding. In this industry, welding plays main role and any defect in welding can lead to disastrous events.Offshore pipe laying is coupled strongly...

Direct-chill (DC) casting is one of the most common methods to produce ingots of high-strength aluminum alloys such as an AA7050. Despite of its superior mechanical properties, this alloy is prone to both hot tearing (HT) and cold cracking (CC) during DC casting. HT form above the solidus while CC occurs below the solidus temperature. CC...

Nowadays, the demand for enhanced performance and reliability in micro and nano systems is growing, especially for fine pitch wafer level integration. Due to reliability and processing issues, lead containing solders are still allowed and being used in high demanding microelectronics bonding application. Potential for reliable environmental...
