  4. 2. Metastable Alumina from Theory: Bulk, Surface, and Growth of κ-Al2O3

    Author : Carlo Ruberto; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density-functional theory; structure; cutting tools; plane waves; first principles; stability; one-dimensional electron gas; DFT; Tasker s rules; ionic crystals; polar surfaces; adsorption; pseudopotentials; Pauling s rules; bonding; surface states; TiC; ceramic materials;

    Abstract : Aluminas are materials of high technological importance that show a fascinating structural flexibility, with a large amount of different phases (alpha, gamma, eta, delta, kappa, chi, ...) and phase transitions at relatively high temperatures. READ MORE

  5. 3. Machining of Some Difficult-to-Cut Materials with Rotary Cutting Tools

    Author : Tero Stjernstoft; KTH; []
    Keywords : Difficult-to-Cut material; Metal Matrix Composite MMC ; Machining; Machinability; Rotary Cutting Tool; Acoustic Emission;

    Abstract : Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. READ MORE

  6. 4. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Author : Pajazit Avdovic; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Abstract : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). READ MORE

  7. 5. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life

    Author : Michael Jacobson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray diffraction; bearing steel; residual stress; fatigue life; cutting conditions; hard turning;

    Abstract : There are many different precision mechanical components such as bearings, fuel injectors, gears and hydraulic components, which are made of hardened steels, and have to be machined to a high degree of precision. Traditionally these components are being ground. READ MORE
