2. 1. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

   Author : Liliana Licea Jimenez; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; electrical properties; photorefractive properties.; polymer matrix nanocomposites; mechanical properties;

   Abstract : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. READ MORE

4. 2. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

   Author : Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Materials science;

   Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE

5. 3. Modelling mechanical properties by analysing datasets of commercial alloys

   Author : Johan Zander; Rolf Sandström; Stanislaw Zajac; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloys; modelling; material optimisation; mechanical properties; solid solution hardening; precipitation hardening; work-hardening; multiple regression; stainless steel; Materials science; Teknisk materialvetenskap;

   Abstract : Commercial alloys are continuously developed to improve their performance. Therefore it is important to develop new optimisation software, which could be used in development of new materials or in materials selection. In this study the mechanical properties which are important in materials selection in mechanical design are investigated. READ MORE

6. 4. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties

   Author : Haiping Cao; Anders Jarfors; Linköpings universitet; []
   Keywords : Mg alloys; microstructure; mechanical properties; defects; modelling; segregation bands; hot tear; mould constraint; semi-solid casting.; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Magnesium is the lightest of all structural metals. As such, and combined  with good mechanical and physical properties, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. READ MORE

7. 5. Transport Properties and Durability of LCP and FRP materials for process equipment

   Author : Stefanie Römhild; Mikael Hedenqvist; Rodney Rychwalski; KTH; []
