  2. 1. Microstructural Development of Nanocrystalline Ni- and Co-Based Materilas upon Annealing

    Author : Melina da Silva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ni; grain growth; nanocrystalline materials; Co-P; Ni-Fe; thermal stability; TEM in-situ annealing;

    Abstract : Nanocrystalline materials are a relatively new group of materials that are constituted by crystals/grains of a few nanometers in size. Because their mechanical, physical and chemical properties are often superior compared to their microcrystalline counterparts, these materials are attractive for many industrial applications.

  4. 2. Development and Characterization of Reliable Graphene-based Materials for Lightweight and Efficient Thermal Management in Electronics

    Author : Markus Enmark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat spreader; vapor chamber; thermal management; thermal interface material; wick structure; reliability testing; graphene;

    Abstract : The semiconductor industry continuously aims to increase the transistor density in integrated circuits to improve performance of electronics. As performance and transistor density increases, so does the power density of integrated circuits. READ MORE

  5. 3. Experimental Studies of Thermal Diffusivities concerning some Industrially Important Systems

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser flash; thermal diffusivity; heat conduction; phonon; electron contribution; crystallisation degree; graphitisation; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The main objective of this industrially important work was to gain an increasing understanding of the properties of some industrially important materials such as CMSX-4 nickel base super alloy, 90Ti.6Al.4V alloy, 25Cr:6Ni stainless steel, 0. READ MORE

  6. 4. Fundamentals of substructure dynamics : In-situ experiments and numerical simulation

    Author : Verity Borthwick; Sandra Piazolo; Dorte Juul Jensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; halite; in-situ; X-ray diffraction; EBSD; annealing; substructure; modelling; Earth sciences; Geovetenskap; Geology; geologi;

    Abstract : Substructure dynamics incorporate all features occurring on a subgrain-scale. The substructure governs the rheology of a rock, which in turn determines how it will respond to different processes during tectonic changes. READ MORE

  7. 5. Thermal Stability of Electrodeposited Nanocrystalline Ni- and Co-Based Materials

    Author : Melina da Silva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocrystalline materials; 3DAP; nanocomposite; thermal stability; TEM; nickel; texture; DSC; cobalt; grain growth; EBSD;

    Abstract : The attractive properties associated with nanocrystalline materials are to a large extent a result of their high intercrystalline volume fraction. However, the intrinsic instability of the nanostructured state may compromise the gain in properties by the occurrence of grain growth during exposure at elevated temperatures. READ MORE
