1. 1. Laser cladded steel - microstructures and mechanical properties of relevance for railway applications

   Författare :Simon Niederhauser; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Cr alloy; Carbon Steel; Microstructure; Internal Stresses; HAZ; Laser Cladding; Co-Cr alloy; Cracking Behaviour; Mechanical Properties; Low Cycle Fatigue;

   Sammanfattning : Owing to increased requirements like increased axle load for railway wheels and rails, new material have to be employed. However, these requirements are mostly surface related, which makes it appropriate to change only the surface layer while keeping the bulk unchanged. LÄS MER

3. 2. Microstructure and Mechanical Properties of Plasma Atomized Refractory Alloys

   Författare :Marina Ciurans Oset; Farid Akhtar; Johanne Mouzon; Dariusz Jarzabek; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma atomization; spherical powder; tungsten carbide; high entropy alloy; refractory; Engineering Materials; Materialteknik;

   Sammanfattning : Plasma centrifugal atomization is a method widely used in the production of spherical powders of metals and alloys with relatively low melting points. A novel plasma centrifugal atomization process suitable for high melting point materials (i.e. 3500 ᵒC and above) was developed by Metasphere Technology AB, currently Höganäs Sweden AB. LÄS MER
