1. 1. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Elsa Friis; Klara Karlsson; Rebecka Damgren; Emma Åkesson; Malin Johansson; [2023]
   Keywords : Hydrogen permeation; PA6; coating; hydrogen permeation barrier; polymer hydrogen permeation; permeation; protective coating; hydrogen embrittlement;

   Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

3. 2. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

   University essay from Linköpings universitet/Tunnfilmsfysik

   Author : Victor Rutberg; [2022]
   Keywords : Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

   Abstract : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. READ MORE

4. 3. Long term aging and creep exposure for advanced heat resistant alloys : A phase analysis

   University essay from Uppsala universitet/Institutionen för materialvetenskap; Uppsala universitet/Institutionen för kemi - Ångström

   Author : Daniel Lundberg; Filip Wilson; Hjalmar Gunnarsson; Leo Sjörén; Robin Xu; Erik Djurberg; [2021]
   Keywords : Austenitic stainless steel; ferritic steels; nickel based alloys; creep; ageing; XRD; SEM EDS; LOM;

   Abstract : This project was ordered by Sandvik Materials Technology and was performed by a group of students at Uppsala university. The purpose of the project was to study precipitation behavior and structure stability in six advanced heat resistant alloys. Each sample were subjected to a creep rupture test in 600 or 700°C depending on the alloy type. READ MORE

5. 4. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Oskar Darselius Berg; [2020]
   Keywords : Technology and Engineering;

   Abstract : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. READ MORE

6. 5. Generation of Engineered Aerosol Stainless Steel Nanoparticles using a Spark Discharge Generator

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Calle Preger; [2016]
   Keywords : aerosol nanoparticles; stainless steel; spark discharge; Technology and Engineering;

   Abstract : This diploma work has shown that it is possible to generate engineered stainless steel nanoparticles using a spark discharge generator (SDG) with a selectable size in the size range 20-70 nm in diameter. The generated particles have similar composition as the electrodes used, although further studies are needed to verify if this is true for all particles generated. READ MORE
