  2. 2. Nanoindentation characterization of high chromium white cast iron for assessment of machining performance

    Author : Ling Chen; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Nanoindentation; FEM; Characterization; High chromium cast iron; Machining; Grid nanoindentation;

    Abstract : As modern production moves towards higher efficiency and cost effectiveness, machining difficult-to-cut materials becomes an increasing challenge. Quickly and reliably characterizing the properties of materials could significantly improve the performance of machining processes in terms of their efficiency and production cost. READ MORE

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

    Author : Kwadwo O. Kese; Bill Bergman; Sture Hogmak; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  4. 4. Characterization of elastic moduli of single fibres

    Author : Shanghong Duan; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFM; Nanoindentation; Shear modulus; Transverse modulus; Carbon fibre;

    Abstract : The carbon fibre is one of most promising materials for high-performance composites since it is lightweight and strong. It has been widely used to build carbon fibre reinforced polymer (CFRP) composites. The carbon fibre dramatically reinforces the composite in the fibre direction. READ MORE

  5. 5. Mechanical Characterisation of Coatings and Composites-Depth-Sensing Indentation and Finite Element Modelling

    Author : Zhi-Hui Xu; KTH; []
    Keywords : dept-sensing indentation; nanoindentation; finite element method; atomic force microscope;

    Abstract : In the past two decades depth-sensing indentation has becomea widely used technique to measure the mechanical properties ofmaterials. This technique is particularly suitable for thecharacterisation of materials at sub-micro or nano scale thoughthere is a tendency to extend its application to the micro ormacro scale. READ MORE
