  2. 1. Synthesis and Characterization of Transition Metal Diborides

    Author : Jimmy Thörnberg; Johanna Rosén; Per Persson; Helmut Riedl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DCMS; HiPIMS; Titanium Diboride; Titanium Aluminum Diboride; Chromium Diboride; Microstructure; Hardness; Oxidation Resistance;

    Abstract : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. READ MORE

  4. 2. Spark Plasma Sintering Enhancing Grain Sliding, Deformation and Grain Size Control : Studies of the Systems Ti, Ti/TiB2, Na0.5 K0.5 NbO3, and Hydroxyapatite

    Author : Mirva Eriksson; Zhijian Shen; Takashi Goto; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spark plasma sintering; plastic deformation; grain growth; titanium; TiB2; hydroxyapatite; Na0.5K0.5NbO3; ferroelectric; transparent; Materials chemistry; Materialkemi; Materials Chemistry; materialkemi;

    Abstract : The unique features of the Spark plasma sintering (SPS) were used to investigate the sintering and deformation behaviour of titanium and titanium–titanium diboride composites, and to control the sintering and grain growth of ferroelectric Na0.5K0.5NbO3 (NKN) and of hydroxyapatite (HAp).

  5. 3. Diffusion bonding of structural ceramics to superalloys by HIP

    Author : Richard Larker; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Diffusion bonding of structural ceramics to superalloys has been investigated. Emphasis was placed on methods resulting in joints durable at elevated temperatures (500 - 700ºC) between these two classes of high - temperature materials. READ MORE
