1. 1. Theoretical modeling of molar volume and thermal expansion

   Författare :Xiao-Gang Lu; Bo Sunsman; Michel Jacobs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; first-principles calculations; ab initio; Calphad; Debye-Grüneisen model; thermodynamic properties; elastic modulus; volume; thermal expansivity; pressure; Thermo-Calc; VASP; element; carbide; nitride; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Combination of the Calphad method and theoretical calculations provides new possibilities for the study of materials science. This work is a part of the efforts within the CCT project (Centre of Computational Thermodynamics) to combine these methods to facilitate modeling and to extend the thermodynamic databases with critically assessed volume data.

3. 2. Metal Expansion Penetration During Solidification of Grey Cast Iron

   Författare :Izudin Dugic; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thennal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; meta! expansion penetration; eutectic cell size.; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The meta! expansion penetration has been examined experimentally. The whole casting process was simulated using a commercial software, in order to investigate the solidification characteristics and the pore formation in the casting studied. LÄS MER

4. 3. The mechanisms of metal expansion penetration during solidification of grey cast iron

   Författare :Izudin Dugic; Preben Norgaard Hansén; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thermal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; metal expansion penetration; eutectic cell size; primary austenite; austenite grain; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The production of high quality castings requires the casting surface to be clean and free from defects. One type of defect often found is caused by metal penetration into the sand mould. LÄS MER

5. 4. Norrlands ekonomi i stöpsleven : ekonomisk expansion, stapelvaruproduktion och maritima näringar 1760-1812

   Författare :Maurits Nyström; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; Northern Sweden; eighteenth and nineteenth century; forest-based staple production; trade; shipping; merchant fleet; shipbuilding; proto-industrialization; economic expansion; conflicts of interests;

   Sammanfattning : This dissertation investigates whether northern Sweden's forest-based staple production and maritime activities were increased and altered in any significant ways prior to the expansion which began just before the middle of the nineteenth century. Furthermore, it studies whether certain changes contributed to thecreation of preconditions for the named expansion. LÄS MER

7. 5. Characterisation of a structural battery composite and its constituents

   Författare :Shanghong Duan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomimetic; carbon fibres; 3D reconstruction.; volume expansion; elastic modulus; characterisation; structural battery electrolyte; structural battery; lithiation;

   Sammanfattning : The structural battery composite is a recently successfully developed multifunctional lithium-ion battery. It is safer and capable to carry mechanical load compared to commercially available liquid electrolyte batteries. LÄS MER
