1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anton Rolseth; [2023]
   Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

   Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

3. 2. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Muhammad Hashir Zaheer; [2023]
   Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

   Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

4. 3. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

5. 4. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

   University essay from Lunds universitet/Industriell Produktion

   Author : Christian Jaunviksna; [2023]
   Keywords : Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

   Abstract : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. READ MORE

6. 5. 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.
