1. 6. Ti3SiC2 synthesis by powder metallurgical methods

   Författare :Ida Kero; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Sammanfattning : The MAX phases constitute a group of ternary ceramics which has received intense attention over the last decade due to their unique combination of properties. The Ti3SiC2 is the most well studied MAX phase to date and it has turned out to be a promising candidate for high temperature applications. LÄS MER

3. 7. 3D-printing for Aerospace : Fatigue Behaviour of Additively Manufactured Titanium

   Författare :Magnus Kahlin; Johan Moverare; Hans Ansell; Gianni Nicoletto; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; fatigue; post processing; crack growth; Ti6Al4V; aerospace; additiv tillverkning; 3D-printing; flyg; utmattning; titan;

   Sammanfattning : Laser powder bed fusion (L-PBF) and electron beam powder bed fusion (E-PBF) are two of the most common additive manufacturing (AM) methods which both provide the engineer with a great freedom of design.This means that parts with light weight, multifunctional applications and improved performance could be achieved through innovative design solutions which have attracted a lot of interest from the aerospace industry.

4. 8. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity

   Författare :Linda Squillaci; Magnus Neikter; Ru Peng; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder Bed Fusion Laser Beam PBF-LB ; Ti-6Al-4V; Microstructure; Particle Size Distribution PSD ; Productivity Enhancement; Pulverbädd additiv tillverkning PBF-LB M ; Ti-6Al-4V; Mikrostruktur; Pulverpartikelstorleksfördelning; Produktivitetsförbättring; Production Technology; Produktionsteknik;

   Sammanfattning : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. LÄS MER

5. 9. Electron beam powder bed fusion of Nitinol : A development from production process window towards delicate structures

   Författare :Lin Zeyu; Amir Rashid; Carolin Körner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Engineering; Industriell produktion;

   Sammanfattning : Electron beam powder bed fusion (PBF-EB) is increasingly attracting attention for manufacturing the near-net shape parts due to its incomparable merits, such as free residual stress and superior mechanical performance. Nickel Titanium (NiTi) as the most widely used functional alloy, has not been systematically explored for manufacturing using PBF-EB despite the perfect vacuum and high temperature manufacturing environment.

7. 10. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

   Författare :Mikael Karlsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

   Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER
