2. 1. Development of Nanostructured Tungsten Based Composites for Energy Applications

   Author : Mazher Ahmed Yar; Mamoun Muhammed; Per-Olov Käll; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tungsten; Nano-tungsten; ODS tungsten; W-La2O3; W-Y2O3; SPS; Plasma-facing materials; Armour material; fusion material;

   Abstract : Tungsten (W) based materials can be used in fusion reactors due to several advantages. Different fabrication routes can be applied to develop tungsten materials with intended microstructure and properties for specific application including nanostructured grades. READ MORE

4. 2. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

5. 3. Towards sustainability in additive manufacturing: material and process aspects

   Author : Tatiana Fedina; Frank Brückner; Alexander Kaplan; Fabian Riss; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

   Abstract : The acceptance of additive manufacturing (AM) depends on the quality of final parts and process repeatability. Recently, many studies have been dedicated to the establishment of the relationship between the process behavior and material performance. READ MORE

6. 4. Modelling Aspects in Forming and Welding of Nickel-Base Superalloys

   Author : Lluís Pérez Caro; Mats Oldenburg; Eva-Lis Odenberger; Juan Carlos Cante Teran; Luleå tekniska universitet; []

   Abstract : The reduction of fuel consumption and carbon dioxide emissions are currently a key factor for the aviation industry because of major concerns about climate change and more restrictive environmental laws. One way to reduce both fuel consumption and CO2 emissions is by significantly decreasing the weight of vehicles while increasing the efficiency of the engine. READ MORE

7. 5. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys

   Author : Toni Bogdanoff; Ehsan Ghassemali; Salem Seifeddine; Anders E.W. Jarfors; Ru Peng; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; defects; material characterization; fatigue performance; digital image correlation;

   Abstract : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. READ MORE
