1. 1. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Minna Olsson; [2023]
   Keywords : metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

   Abstract : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. READ MORE

3. 2. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

   University essay from Lunds universitet/Industriell Produktion

   Author : Cornelis Botermans; [2023]
   Keywords : Technology and Engineering;

   Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

4. 3. Nanoscale characterisation of model Ni-Mo catalyst active phases

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Jonas Elmroth Nordlander; [2022]
   Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

   Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

5. 4. Design of Experiment and Evaluation of Abrasive Waterjet Cutting in Titanium Alloy Sheet

   University essay from

   Author : Daniel Andersson; Mikael Ingvarsson; [2019-07-03T13:52:34Z 2019-07-03T13:52:34Z 2015]
   Keywords : Materialvetenskap; Produktion; Mekanisk tillverkningsteknik; Materials Science; Production; Mechanical manufacturing engineering;

   Abstract : High demands on components in the aerospace industry empower the use of advanced manufacturing processes in order to increase quality and reduce costly processing steps. This includes non-conventional machining such as Abrasive Waterjet where the components are cut through abrasive impingement by means of abrasives accelerated by pressurized water. READ MORE

6. 5. Understanding Sn-seeded InSb nanowire growth

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

   Author : Hengfang Zhang; [2017]
   Keywords : Science General;

   Abstract : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. READ MORE
