  2. 6. Numerical investigation on the formation mechanism of residual stress in metal cutting

    Author : Yang Liu; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; FEM; ; Metal cutting; Thermal-mechanical load; Plastic deformation;

    Abstract : Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. READ MORE

  4. 7. Adhesion and Residual Stress Characterization of HVOF Sprayed Inconel 718 Coatings

    Author : Christophe Lyphout; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVOF; Residual Stress; Inconel 718; Thermal spray; Adhesion Strength; Finite Element Method; High Velocity Oxy-Fuel;

    Abstract : Thermal spray technology in general is nowadays recognized as an industrial process, mature enough to apply coatings on different substrate materials that protect parts against wear, corrosion, heat, or combinations of these. The quality demands on coating homogeneity and adhesion strength are, nowhere more than in the automotive and aeronautic industries, continuously increasing. READ MORE

  6. 9. Relaxation and nanomechanical studies of the vickers residual stress field in glass

    Author : Kwadwo O. Kese; Bill Bergman; Sture Hogmak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; soda-lime glass; vickers residual stress field; nanoindentation; stress rekaxatuib; cube corner indenter; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. READ MORE

  7. 10. 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
