11. Modelling and experimental evaluation of non-linear fatigue crack propagation in a ductile superalloy
Sammanfattning : Fatigue life evaluation is an important part in the design process of an industrial gas turbine. The fatigue life can be divided into crack initiation and crack propagation, and not to address the crack propagation part usually yields a non-conservative and overcomplicated design. LÄS MER
12. Carbon Based Materials Synthesis and Characterization for 3D Integrated Electronics
Sammanfattning : 3D IC packaging technology extends Moore’s law and shifts the IC field into a new generation of smaller, but more powerful devices. Interconnection and thermal management as two critical parts of 3D IC integration packaging, are facing harsh challenges due to the miniaturization of IC devices. LÄS MER
13. Microscale electrostatic 2D- and 3D-printing
Sammanfattning : There has been an explosive interest in 2D- and 3D-printing production methods during the past decade due to the ability to rapidly create almost arbitrary structures. Challenges of printing control are encountered for instance when pushing the methods to produce smaller and smaller structures. LÄS MER
14. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics
Sammanfattning : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. LÄS MER
15. Atmospheric corrosion of Mg and MgAl alloys – characterization and mechanisms
Sammanfattning : The atmospheric corrosion of Mg and MgAl alloys was investigated. Corrosion tests were performed in the laboratory under controlled environment. CP Mg, AM50 and AZ91 samples were exposed at 95% RH and 22°C in the presence and in the absence of 400 ppm CO2 for 24 h to 672 h. The passive film was characterized by means of XPS, FTIR, AES and XRD. LÄS MER
