1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy
Master-uppsats, Jönköping University/JTH, Material och tillverkningSammanfattning : 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. LÄS MER
2. Evaluation of in-situ technology performance and decision analysis by combining economic and environmental impact analysis for a case study
Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : In the contemporary global context, the global focus on reducing environmental impacts in any formats has intensified. This study intends to assess the environmental impacts and life cycle costs associated with the A1-A5 stages (production and construction stages) of the Köping Port project and eight additional proposed scenarios.

3. Modelling Gas Flow Behaviour in Gas Atomizer
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

4. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER
5. Supercooling Simulation of Latent Heat Based Storage : A simulation model built in COMSOL Multiphysics
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The energy demand in the building sector makes up a large portion of our energy consumption. The industrial sector is also energy intense and oftentimes loses a great deal as surplus heat. LÄS MER
