11. The rational design of lithium insertion materials for battery applications
Sammanfattning : The transition-metal oxide spine1 LiMn2O4 is a promising cathode material for high-capacity lithium-ion batteries. Structure-property relationships pertaining to the electrochemical cycling behaviour of LiMn2O4 have been studied. LÄS MER
12. Pressure-Induced Amorphization and Distinct Amorphous States of Clathrate Hydrates
Sammanfattning : This thesis summarizes a study on the pressure-induced amorphization (PIA) and structures of amorphous states of clathrate hydrates (CHs).PIA involves the transition of a crystalline material into an amorphous solid in response of mechanical compression at temperatures well below the melting point.

13. Precipitation in Advanced Stainless Steels
Sammanfattning : Advanced stainless steels often suffer from complex precipitation behaviour due to the high levels of alloying elements needed to obtain their attractive properties. This demands a correct handling of the material to avoid formation of harmful phases during production, manufacturing and service. LÄS MER
14. Tin-based Glasses: Structure and Electrochemical Properties
Sammanfattning : This thesis presents an investigation of microscopic structure and electrochemical properties, and their relationship, for various tin-based borate, phosphate and borophosphate glasses. Tin-based glasses have attracted a lot of scientific interest as anode materials in Li-ion batteries. LÄS MER
15. Microstructure and mechanical properties of low-temperature hot isostatic pressed Ti-6Al-4V manufactured by electron beam melting
Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER
