6. Low Temperature Austenite Decomposition in Carbon Steels
Sammanfattning : Martensitic steels have become very important engineering materials in modern society. Crucial parts of everyday products are made of martensitic steels, from surgical needles and razor blades to car components and large-scale excavators. LÄS MER
7. Modelling microstructure evolution of weld deposited Ti-6Al-4V
Sammanfattning : The microstructure and consequently the mechanical properties of titanium alloys are highly dependent on the temperature history endured by the material. The manufacturing process of metal deposition induces repetitive cooling and heating in the material determining a specific microstructure. LÄS MER
8. Does Bainite form with or without diffusion? : The experimental and theoretical evidence
Sammanfattning : With the increased interest in bainitic steels, fundamental understanding of the bainite transformationis of major importance. Unfortunately, the research on bainite has been hampered by an oldcontroversy on its formation mechanism. Over the years two quite different theories have developedclaiming to describe the bainite transformation i.e. LÄS MER
9. Time-Resolved and High-Energy Synchrotron Radiation Crystallography using X-ray Area Detectors: Calibration and Applications
Sammanfattning : This thesis relates to characterisation and calibration techniques for X-ray area detectors with applications in time-resolved and high-energy X-ray crystallography. X-ray crystallography is an interdisciplinary science with important applications in many fields, e.g. chemistry, physics, biology, geology and materials science. LÄS MER
10. Phase change with stress effects and flow
Sammanfattning : In this thesis two kinds of phase change i.e., solid state phase transformation in steels and solid-to-liquid phase transformation in paraffin, have been modeled and numerically simulated. LÄS MER
