6. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing
Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.

7. Surface Integrity and Fatigue Performance of Nickel-based Superalloys
Sammanfattning : Due to global warming, the demand for more efficient gas turbines has increased. A way to achieve this, is by increasing the operating temperature of the gas turbine. Therefore, nickel-based superalloys have been developed to withstand these extreme temperatures and loads, especially in the hot sections. LÄS MER

9. Cryogenic Machining of Ti-6Al-4V
Sammanfattning : The use of cryogenic coolants such as liquid nitrogen or liquid carbon dioxide has emerged as a sustainable alternative to conventional cutting fluids during machining operations, with the potential to increase tool life, leading to productivity gains, as well as to improve the surface integrity of the machined components. In addition, the machined surfaces are left residue-free after the process and there are no used cutting fluids to dispose of. LÄS MER
10. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity
Sammanfattning : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. LÄS MER
