  1. 1. Tribological characterisation of additively manufactured hot forming steels

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

    Author : Anna Vikhareva; [2020]
    Keywords : High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

    Abstract : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. READ MORE

  3. 2. The influence of microstructural deformations and defects on mechanical properties in cast aluminium components by using Digital Image Correlation Techniques (DICT)

    University essay from Högskolan i Jönköping/Tekniska Högskolan

    Author : Jahanmehr Armanjo; [2015]
    Keywords : Al-Si cast alloys; AlSi7Mg0.3; strontium modification; heat treatment; SDAS Secondary Dendrite Arm Space ; Aramis; digital image correlation technique DICT ; mechanical properties ultimate tensile strength; offset yield strength and elongation ; plaster mould processes;

    Abstract : Digital image correlation techniques (DICT), a non-contact deformation measuring technique based on gray value digital images, have become increasingly used over the last years. By using the DIC technique during a tensile test, the deformation behavior of different engineering material under an applied load can be determined and analyzed. READ MORE

  4. 3. Influence of ageing process on the microstructure and mechanical properties of aluminium-silicon cast alloys - Al-9%Si-3%Cu and Al-9%Si-0.4%Mg

    University essay from JTH, Maskinteknik

    Author : Krzysztof Kwapisz; Marcin Gwóźdź; [2008]
    Keywords : Aluminium; Solution heat treatment; Ageing; Mechanical properties;

    Abstract : The aim of this thesis is to investigate the influence of ageing process on the microstructure and mechanical properties of aluminium-silicon alloys. The investigation was carried on Al-9%Si-3%Cu and Al-9%Si-0.4%Mg. To obtain different DAS with low content of oxide films and micro shrinkage, gradient solidification has been used. READ MORE

  5. 4. The influence of Mn on the microstructure and mechanical properties of Al-Si based alloys containing Fe

    University essay from JTH, Maskinteknik

    Author : Lennart Lindrud; Göran Lindgren; [2006]
    Keywords : Aluminum; Silicon; Manganese; Casting; Fe; Mechanical Properties; SDAS; Tensile Test; Heat Treatment;

    Abstract : Abstract The purpose of this research is to investigate the influence of Manganese (Mn) on cast aluminum alloys where a substantial amount of Iron (Fe) is included. Ductility and tensile strength need to be improved in recycled aluminum alloys where greater amounts of Fe are found. READ MORE
