16. Efficient crystal plasticity simulations of microstructure evolution
Sammanfattning : One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. LÄS MER
17. Microstructural investigation of CVD TiAlN, TiN and WN coatings
Sammanfattning : High speed machining of workpiece materials puts extreme thermal and pressure loads onto the cutting tool inserts, which thus must possess both high hardness and good toughness. Nowadays, most cutting tools are made of cemented carbide substrates that are coated with wear-resistant coatings. LÄS MER
18. Key Components for High Tc SQUID Magnetometers
Sammanfattning : This thesis describes the development of key components for superconducting quantum interference device (SQUID) magnetometers in the high temperature superconductor YBa2Cu3O7 (YBCO). Such magnetometers are made for liquid nitrogen temperature operation, as opposed to low Tc devices that are confined to liquid helium. LÄS MER
19. Grain Boundary Structure of YBa2Cu3O7-δ High Tc Superconductors
Sammanfattning : The microstructures of YBa2Cu3O7-.delta. (YBCO) high Tc superconducting materials have been studied using analytical electron microscopy. The effects of processing parameters on the interfacial microstructures have been investigated in both bulk materials and thin films. LÄS MER
20. Investigation and modelling of friction stir welded copper canisters
Sammanfattning : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. LÄS MER
