  1. 1. Microstructural Evolution In As-cast Alloys during Plastic Deformation

    Author : Mitra Basirat; Pär Jönsson; Hasse Fredriksson; Jacques Lacaze; KTH; []
    Keywords : plastic deformation; compression test; recrystallization; deformation band; As-cast; microsegregation; carbide dissolution; disordered structure; order disorder transformation; twining; steel; β brass; copper; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Abstract : The effect of deformation on microstructural changes in metals and alloys is the subject of considerable practical interest. The ultimate goal is to control, improve and optimize the microstructure and texture of the finished products produced by metal forming operations. READ MORE

  2. 2. Synthesis and Characterization of Ternary Carbide Thin Films

    Author : Ola Wilhelmsson; Ulf Jansson; Michael Stueber; Uppsala universitet; []
    Keywords : Chemistry; Thin film; dc magnetron sputtering; tribology; carbide; PVD; MAX-phase; DFT; solid solution; Kemi;

    Abstract : This thesis reports on synthesis, microstructure and properties of binary and ternary carbide thin films deposited by dc magnetron sputtering. These materials are interesting since they exhibit a wide range of useful properties, such as high hardness, resistance to wear and oxidation, and high electrical conductivity. READ MORE

  3. 3. Carbide and MAX-Phase Engineering by Thin Film Synthesis

    Author : Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Abstract : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. READ MORE

  4. 4. Mechanisms of Plastic Deformation of Cemented Carbide and Cermet Cutting Tools

    Author : Gustaf Östberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SEM; cermets; TEM; plastic deformation; ab initio calculations; EFTEM; APFIM; FIB; cemented carbides; EBSD;

    Abstract : In this thesis, the physical mechanisms acting during plastic deformation of hardmetals used in metal cutting applications have been investigated. Microstructural and microanalytical studies have been performed on cemented carbides as well as cermet materials. READ MORE

  5. 5. Insights into wear and deformation of alternative binder hardmetals

    Author : Lisa Toller-Nordström; Susanne Norgren; Ben Britton; Uppsala universitet; []
    Keywords : hardmetal; cemented carbide; alternative binders; steel turning; electron microscopy; electron diffraction; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : This work presents new insights into how hardmetals with alternative binders as well as cobalt based references react to wear and deformation. The main focus has been on hardmetals for steel turning, but also on studying certain fundamental properties of the new binder materials. READ MORE
