    Sammanfattning : Anandamide (AEA) is an endogenous fatty acid which activates the same cannabinoid receptors as ∆9-tetrahydrocannabinol, the psychoactive substance in marijuana. In vivo, anandamide exerts a number of actions including effects upon pain and inflammation. LÄS MER

  4. 3. Modeling the Microstructural Evolution during Hot Deformation of Microalloyed Steels

    Författare :Linda Bäcke; Stefan Jonsson; Eric J. Palmiere; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling; austenite; microalloyed steels; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization<; Materials science; Teknisk materialvetenskap;

    Sammanfattning :   This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. LÄS MER

    Sammanfattning : Cattle are often portrayed as a male affair in Botswana. However, venturing out into the Kalahari countryside to scratch the surface of this state of affairs, another picture emerges. LÄS MER

  7. 5. 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
