  1. 1. A TEM Investigation of Contact between Nanoparticles

    Författare :Yiming Yao; Chalmers University of Technology; []
    Nyckelord :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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. On the low primary water stress corrosion cracking susceptibility of weld deformed Alloy 690

    Författare :Rickard Shen; Pål Efsing; Jonas Faleskog; Grace Burke; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : It has been shown in recent years that the nickel-base Alloy 690 can become susceptible to stress corrosion cracking (SCC) in the primary water of nuclear power plants with pressurized water reactors if it has been sufficiently deformed at room temperature. Although the material is not intentionally used in a deformed state, it can become deformed by various manufacturing processes. LÄS MER
