  1. 1. Development of tools for integrated optimisation and use of aluminium alloys

    Författare :Johan Zander; Rolf Sandström; Bjørn Holmedal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloys; Modelling; Materials optimisation; Mechanical properties; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is useful to establish new optimisation software, which could be used in development of new materials or in materials selection. LÄS MER

  3. 2. High Performance Aluminium Alloys for Laser Powder Bed Fusion: Alloy Design and Development

    Författare :Bharat Mehta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Precipitation Kinetics; Integrated Computational Materials Engineering; Laser Based Powder Bed Fusion; Heat Treatment; Aluminium Alloys;

    Sammanfattning : Additive Manufacturing (AM), particularly Laser Based Powder Bed Fusion (LB-PBF) has proven to be a notable technology to produce novel microstructures and expand the ceiling of product design. However, the development of novel alloys in metal LB-PBF has not followed the same pace as development of product design. LÄS MER

  4. 3. Development of high performance aluminium alloys tailored for powder bed fusion-laser beam

    Författare :Bharat Mehta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation kinetics; Powder bed fusion-laser beam; Aluminium alloys; Integrated computational materials engineering; Additive manufacturing; Alloy design; Heat treatments;

    Sammanfattning : The powder bed fusion-laser beam (PBF-LB) process has lately been regarded as a top choice for creating complicated structures which are not possible via conventional manufacturing. Nevertheless, the pace of alloys for PBF-LB has been slower. LÄS MER

  5. 4. Modelling mechanical properties by analysing datasets of commercial alloys

    Författare :Johan Zander; Rolf Sandström; Stanislaw Zajac; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloys; modelling; material optimisation; mechanical properties; solid solution hardening; precipitation hardening; work-hardening; multiple regression; stainless steel; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. LÄS MER

  7. 5. The Effect of Processing Parameters and Alloy Composition on the Microstructure Formation and Quality of DC Cast Aluminium Alloys

    Författare :Majed Jaradeh; Torbjörn Carlberg; Lars Arnberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium wrought alloys; AA3xxx and 6xxx; Direct Chill Casting; Unidirectional Solidification; Bridgman technique; Process parameters; Microstructure; Composition modification; Thermal analysis; Inclusions; Metallographical investigations; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The objective of this research is to increase the understanding of the solidification behaviour of some industrially important wrought aluminium alloys. The investigation methods range from direct investigations of as-cast ingots to laboratory-scale techniques in which ingot casting is simulated. LÄS MER
