  2. 1. The Effect of Long Range Order on Elastic Properties of Alloys

    Author : Guisheng Wang; Levente Vitos; Balázs Ujfalussy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; long-range order; elastic constant; alloys; magnetic; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Abstract : Ab initio alloy theory, formulated within the exact muffin-tin orbitals method in combination with the coherent-potential approximation, is used to determine the effect of long range order on the elastic properties. The lattice parameters and single-crystal elastic constants of Cu3Au are calculated for different partially ordered structures ranging from the fully ordered L12 to the random face centered cubic lattice.

  4. 2. 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.
