1. 16. Material Properties of Cereal Protein Films

   Författare :Thomas Gillgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasticization; avenin; prolamin; kafirin; mechanical properties; water vapour permeability; oxygen permeability; protein; film; glass transition temperature; zein;

   Sammanfattning : Materials that are renewable and biodegradable are demanded due to environmental aspects. Biopolymeric materials, such as materials from prolamins, fulfil both of these requirements. Prolamins are cereal storage proteins. Examples of such are zein, gluten, kafirin and avenin from maize, wheat, sorghum and oats, respectively. LÄS MER

3. 17. Laser powder bed fusion of 316L stainless steel - Microstructure and mechanical properties as a function of process parameters, design and productivity

   Författare :Alexander Leicht; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; productivity; design for additive manufacturing; additive manufacturing; thin-wall structures; stainless steel; laser powder bed fusion; microstructure; 316L;

   Sammanfattning : One of the most common additive manufacturing techniques for fabricating metallic components is laser powder bed fusion, which has demonstrated great potential in fabricating parts with properties exceeding the properties achieved via conventional methods. To fully utilize the process’s potential, a more profound understanding of the microstructure and properties of the laser powder bed fusion processed material is required. LÄS MER

4. 18. Additively Manufactured Inconel 718 : Microstructures and Mechanical Properties

   Författare :Dunyong Deng; Johan Moverare; Ru Lin Peng; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Additive manufacturing (AM), also known as 3D printing, has gained significant interest in aerospace, energy, automotive and medical industries due to its capabilities of manufacturing components that are either prohibitively costly or impossible to manufacture by conventional processes. Among the various additive manufacturing processes for metallic components, electron beam melting (EBM) and selective laser melting (SLM) are two of the most widely used powder bed based processes, and have shown great potential for manufacturing high-end critical components, such as turbine blades and customized medical implants.

5. 19. Wood fiber composites : processing, structure and properties

   Författare :Lars-Olof Nordin; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Sammanfattning : The goal of this work has been to investigate how to make wood polymer composite materials with good mechanical properties, which also could be tailored for different applications. The fundamental idea behind the work was that good mechanical properties of the composite material require that the stiffness and strength of the wood cell wall material are really utilized. LÄS MER
