1. 6. Chip Management in Milling and Drilling of Ductile Cast Iron

   University essay from Lunds universitet/Industriell Produktion

   Author : Alexander Jönsson; Giacomo Aliboni; [2023]
   Keywords : Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

   Abstract : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.

3. 7. Modeling of Energy Consumptionin Milling Process to Assess their Environmental Impact

   University essay from KTH/Produktionsutveckling

   Author : Vasanth Kumaran Ashok Kumar; Peng Liang; [2023]
   Keywords : Milling process; Energy consumption; Mechanistic model; Environmental impact; Life cycle assessment; Fräsningsprocess; Energiförbrukning; Mekanisk modell; Miljöpåverkan; Livscykelbedömning;

   Abstract : This thesis presents a method for modeling energy consumption in the milling process to assess their environmental impact, using a simple experimental approach. The factors influencing the environmental impact in milling processes are analyzed with life cycle assessment principles, and their climate change impact is calculated with examples of dry milling experiments.

4. 8. Synthesis of glass-ceramic Li2S-P2S5-based electrolyte for solid-state batteries

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Leo Sjörén; [2023]
   Keywords : Solid electrolyte; Battery; sulphide; glass; electolyte; ball milling; ceramic; glass-ceramic; Batteri; elektrolyt; glas; glaskeram; svavel;

   Abstract : In this project, solid sulphur based Li3PS4 electrolytes doped with Li4SiO4 were synthesised using two methods. In method A, a bought β-Li3PS4 electrolyte from Nei Corp was doped with 5 mole per cent Li4SiO4, resulting in a glass-ceramic electrolyte. READ MORE

5. 9. Experimental studies of radiation damage in uranium nitride

   University essay from KTH/Fysik

   Author : Maria Giamouridou; [2023]
   Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

   Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

6. 10. Developing an Ar milling process to improve the contact quality to InAs nanowires

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Chris Mkolongo; [2023]
   Keywords : InAs nanowires; Argon milling; Technology and Engineering;

   Abstract : The aim of this work was to develop a stable and reproducible argon milling process for InAs nanowires to remove the native oxide layer that increases electrical resistance. This was done by identifying a few milling parameters and studying them in relation to the milling rate of silicon dioxide (SiO2). READ MORE
