  1. 1. A TEM Investigation of Contact between Nanoparticles

    Författare :Yiming Yao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LACBED; CBED; nanoparticles; interface; adhesion; image simulation; energy filtering; misorientation; contacting; strain field TEM;

    Sammanfattning : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. LÄS MER

  5. 4. Deformation Behaviour, Microstructure and Texture Evolution of CP Ti Deformed at Elevated Temperatures

    Författare :Zhipeng Zeng; Stefan Jonsson; Hans J. Roven; Bevis Hutchinson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercially pure titanium; Zener–Hollomon parameter; Dynamic recovery; Dynamic recrystallization; Recrystallized volume fraction; Grain size; Flow stress; Constitutive equation; Texture; High angle grain boundary; Low angle grain boundary; Deformation twinning; Schmid factor; Misorientation; Hot compression; Slip system; Subgrain; EBSD; Construction materials; Konstruktionsmaterial;

    Sammanfattning : In the present work, deformation behavior, texture and microstructure evolution of commercially pure titanium (CP Ti) are investigated by electron backscattered diffraction (EBSD) after compression tests at elevated temperatures. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. LÄS MER

  7. 5. Functional Interfaces in Epitaxial YBa2Cu3O7-δ with Artificial Grain Boundary Junctions

    Författare :Henrik Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The properties of superconducting devices based on grain boundaries in YBa2Cu3O7-δ (YBCO) thin films are determined by the atomic structure of the grain boundary plane. To obtain these devices based on single grain boundaries, biepitaxial fabrication techniques has been used. LÄS MER
