  2. 1. Dynamic and meta-dynamic recrystallization of Ni-based superalloy Haynes 282

    Author : Emil Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot compression; EBSD; dynamic recrystallization; meta-dynamic recrystallization; Ni-base superalloys;

    Abstract : Thermomechanical processes are a crucial manufacturing step because they can “reset” the microstructure, and set the starting point for all following steps. In turn, the microstructure can be used to tailor the mechanical properties of the material. READ MORE

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

    Author : Izudin Dugic; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Articulating The User : a Discursive-Material Analysis of Humans in Interdisciplinary Design Collaborations

    Author : Paulina Rajkowska; Annika Waern; Patrick Prax; Jeffrey Bardzell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; user; HCI; design; discourse; meta-study; qualitative; museums; innovation; Människa-dator interaktion; Human-Computer Interaction;

    Abstract : Technology design taking place in interdisciplinary collaborations is a complicated process which, due to the nature of available research funding, shapes much of the research that falls under the umbrella of Research through Design (RtD). This dissertation is a meta-study of an EU funded research and innovation project, GIFT, situated in the domain of museum technology and involving multiple partners. READ MORE

  6. 4. Optical metasurfaces for momentum exchange between light and matter

    Author : Mohammad Mahdi Shanei; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical forces and torques; phase-gradient metasurface; particle transport; optical momentum exchange; Flat optics; rotary meta-motor; meta-particle;

    Abstract : Light carries energy and momentum that can be transferred to matter. Because of the conservation of total momentum, a change in light momentum due to interaction with an object must be compensated by an equal but opposite change in the momentum of that object. READ MORE

  7. 5. First principles study of tungsten-based alloys: From defect thermodynamics to phase diagrams

    Author : Leili Gharaee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural materials; first-principles calculations.; point defects; tungsten alloys; irradiation;

    Abstract : Nuclear fusion is a very attractive option for energy production as it is clean, safe and efficient. The major obstacle in construction of fusion power plants is the development of materials that can tolerate the extreme operational condition especially high-energy neutron flux. READ MORE
