4. 2. Laser powder bed fusion processing and heat treatment of Ni-base superalloys: microstructure and properties

   Author : Abdul Shaafi Shaikh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure.; Additive manufacturing; heat treatment; Inconel 939; Haynes 282; superalloys; powder bed fusion – laser beam;

   Abstract : Nickel-base superalloys are indispensable materials for the energy and aerospace industries. The additive manufacturing (AM) of these materials by powder bed fusion – laser beam (PBF-LB) presents a valuable opportunity to improve component performance and ease manufacturing and supply chain complexity in these industries.

5. 3. Energy efficiency and the challenge of climate change - Studies of the Swedish building sector

   Author : Jonas Nässén; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology diffusion; input-output analysis; Energy efficiency; Swedish building sector; carbon dioxide;

   Abstract : The interrelated environmental, social and economic challenges imposed by global climate change will make it one of the central political issues in the coming century. Use of fossil fuels is the largest source of anthropogenic CO2 emissions and hence the transformation of the energy system plays a central role in the mitigation of future climate change. READ MORE

6. 4. Prestressed hybrids of AAC and HPC : The BCE (Block Composed Element) building system. A conceptual study

   Author : Hamid Bagheri; Bo Göran Hellers; Jonas Holmgren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

   Abstract : There is an important potential for a development of a building system, if the present AACblock plants are completed with high performance concrete and pre-stressing technique. This can be done as a continuation of a present AAC production or in a site factory. Hybrid cooperation between AAC and concrete is not a new technology. READ MORE

7. 5. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

   Author : Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

   Abstract : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. READ MORE
