  1. 21. Treatment of a Liquid Al-Si Alloy : Quality Control and Comparison of Two Melt Degassing Processes

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Badreddin Radwan; [2020]
    Keywords : Dissolved Hydrogen; Degassing; Porosity; Grain Refinement; Eutectic Modification; Fluidity; Metallography; Thermal Analysis.;

    Abstract : Products manufactured by aluminium casting have become very popular and already replaced many parts that were once produced by iron and steel casting. This trends upwards especially in the automotive industry as it has become extremely important to reduce vehicle weight due to environmental requirements and economical aspects. READ MORE

  3. 22. Measuring resistivity in a contactless fashion

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Jim Klintrup; [2020]
    Keywords : resistivity; magnetic; field; diffusive; eddy; current; coils; Physics and Astronomy;

    Abstract : The aim of this thesis work was to develop a rig to measure the resistivity of a metal sample. The initial testing of the rig would be done at room temperature and calibration of the setup would be done with aluminum samples and then metallic alloys would be studied. READ MORE

  4. 23. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates

    University essay from KTH/Materialvetenskap

    Author : Monika Rolinska; [2020]
    Keywords : Extraction replica; transmission electron microscopy; materials characterization; precipitation; Extraktionsrepliker; transmissionselektronmikroskopi; materialkaraktarisering; utskiljningar;

    Abstract : Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.

  5. 24. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

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

    Author : Gabriel Macêdo; [2020]
    Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

    Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

  6. 25. Friction and material modelling in Sheet Metal Forming Simulations

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Herman Bentsrud; [2020]
    Keywords : Sheet metal forming; Material model; Triboform; Autoform; Plåtmetalformning; Materialmodell; Triboform; Autoform;

    Abstract : In today’s car manufacturing industry, sheet metal forming is a important process that takes preparation, which is time consuming and complex when new processes are made. When new metal grades and alloys are provided to the industry, tests are conducted to determine it’s behaviour and strengths. READ MORE
