  3. 2. Inhomogenity in microstructures

    Författare :Jacek Komeda; KTH; []
    Nyckelord :;

    Sammanfattning : The purpose of the present thesis is to quantitativelycharacterise structural features which contribute to thematerial anisotropy and to relate developed parameters to thematerial properties. Various forms of structural inhomogeneitywere quantified with the help of comuterised image analysisusing quantitative metallography and statistical analysismethods. LÄS MER

  4. 3. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties

    Författare :Dunyong Deng; Johan Moverare; Ru Lin Peng; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.

  5. 4. Shaping of Food Microstructures

    Författare :Lars Hamberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food microstructure; flow; emulsion; carrageenan whey protein isolates; shaping; aggregate; gelatine; suspension; gel formation; particle; Fourier shape description; shape; shape measurements;

    Sammanfattning : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.

  7. 5. Engineering of metal microstructures : process-microstructure-property relationships for electrodeposits

    Författare :Jens A. D. Jensen; Dieter Landolt; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The relationships between growth-conditions, topography and microstructure, and physical properties of electrochemically deposited copper, nickel and zinc-iron alloys were studied. Growth was investigated while systematically varying process parameters such as electrolyte chemistry, type and concentration of additives, current density, and mass transport. LÄS MER
