  3. 2. 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

  5. 4. Environmental assessment of emerging technologies: the case of biopolymers

    Författare :Selim Nouri; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; life cycle assessment; cost assessment; environmental assessment; process modeling; biopolymer;

    Sammanfattning : Current efforts to mitigate climate change, using renewable resources and reducing waste, drives the development of new industrial processes. In this study we examine the technologies for conversion of biomass to plastics. LÄS MER

  7. 5. Palladium-catalyzed C-H functionalization of alkenes under oxidative conditions

    Författare :Johanna M Larsson; Kálmán Szabó; Eszter Borbas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The unique properties of high oxidation state palladium have been used to develop new catalytic alkene C-H functionalization reactions. A Heck-type coupling based on the reactivity of palladium catalysts and diaryliodonium salts has been developed with broad synthetic scope and tolerance for functional groups that are ordinarily reactive in Pd0/PdII catalysis, for example, allylic acetates and aryl bromides.
