1. Investigating the effect of grinding method on ore beneficiation behaviour
Master-uppsats, Luleå tekniska universitet/Mineralteknik och metallurgiSammanfattning : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. LÄS MER
2. Supervised Machine Learning Modeling in Secondary Metallurgy : Predicting the Liquid Steel Temperature After the Vacuum Treatment Step of the Vacuum Tank Degasser
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In recent years the steelmaking industry has been subjected to continuous attempts to improve its production route. The main goals has been to increase the competitiveness and to reduce the environmental impact. The development of predictive models has therefore been of crucial importance in order to achieve such optimization. LÄS MER
3. Automatic segmentation of microstructures in metals : A computer vision approach
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The microstructures of a metal determine the physical, electrical and chemical properties of the metal, and analysis of microstructures is therefore an important part of materials science. Modern microscopes are capable of generating a lot of high-quality micrographs in a short period of time. LÄS MER
4. Vikingatida svärd på Gotland : Ett metallurgiskt perspektiv
Kandidat-uppsats, Uppsala universitet/ArkeologiSammanfattning : Research about viking age swords is nothing new but for a long time the main focus have been different aspects of typologies which have evolved since early 20th century. During the last 30 years the still growing communities of Viking reenactment have shed new light upon the fighting skills of pre Christian Nordic societies. LÄS MER
5. Process Optimization and Characterization of Inconel 718 Manufactured by Metal Binder Jetting
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The development of a process chain for Inconel 718 production utilizing Binder Jetting has been investigated. Different powder sources were compared by the effect they had on machine compatibility, powder bed packing, recyclability, green density, sintering parameters, final density, porosity, and mechanical properties.
