  1. 1. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

    Master-uppsats, Jönköping University

    Författare :Ruslan Sevastopolev; [2020]
    Nyckelord :High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

    Sammanfattning : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. LÄS MER

  3. 2. Development of aluminium-silicon alloys with improved properties at elevated temperature

    Magister-uppsats, Högskolan i Jönköping/JTH, Material och tillverkning

    Nyckelord :Al-Si alloy; Nickel; Cobalt; Elevated temperature properties; Microstructure;

    Sammanfattning : Aluminium-silicon alloys have gained increasing market share in the automotive and aerospace industry because of increased environmental demands. These alloys have a high strength-to-weight ratio, good corrosion resistance, castability and recycling potential. LÄS MER

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

    Master-uppsats, Högskolan i Jönköping/Tekniska Högskolan

    Författare :Jahanmehr Armanjo; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, JTH, Maskinteknik

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

    Sammanfattning : 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. LÄS MER
