1. 1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

   University essay from KTH/Materialvetenskap

   Author : Christopher Hallén; Marcus Johansson Storne; [2023]
   Keywords : ;

   Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

3. 2. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

4. 3. Reduction of Explosion Effects by Use of a Sandwich Wall

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Annie Bohman; [2023]
   Keywords : Explosion Blast load Sandwich wall Energy absorption; Technology and Engineering;

   Abstract : It was recently decided that a new hospital is to be built in Växjö. It is important that hospitals can be utilised no matter the circumstances, even in situations of threat. New reports have been published concerning how hospitals are to be designed. In this, it is mentioned that explosions are a threat that should be considered. READ MORE

5. 4. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Patricio Piantanida; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; cryogenic;

   Abstract : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials.
