1. 1. Modeling of Precipitation by Structural Phase-Field Crystal Method

   University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

   Author : Jacob Holmberg-Kasa; [2021]
   Keywords : strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

   Abstract : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. READ MORE

3. 2. Economic and technic aspects on post-weld treatment of welded structures exposed to fatigue loads

   University essay from KTH/Industriell produktion

   Author : Johan Ankre; [2021]
   Keywords : ;

   Abstract : It has been known for a long time that we live on a planet with a limited stock of resources. The world population is increasing, more products are being produced and humans are consuming more in a lifetime than the planet can recover. It is a constant competition between industries to keep their prices down and get consumers to buy their product. READ MORE

6. 5. Residual stresses in Ti-6Al-4V from low energy laser repair welding

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Peter Ericson; [2018]
   Keywords : Micro laser welding; Low energy welding; Ti-6Al-4V; Ti64; Residual stress; Response Surface Methodology; Repair welding; Welding simulation; Mikrolasersvetsning; Lågenergetisk svetsning; Lågenergisvets; Ti-6Al-4V; Ti64; Restspänningar; Response Surface Methodology; Reparationssvets; Svetssimulering;

   Abstract : Millimeterstora och svårupptäckta defekter kan uppstå internt i stora och komplexa gjutgods av Ti-6Al-4V, ibland går dessa oupptäckta tills detaljen genomgått mekanisk bearbetning och en stor kostnad redan har gått in i den. Dessa defekter och andra industriella olyckshändelser leder till ett behov av additiva reparationsmetoder där den för tillfället rådande metoden är TIG-svetsning. READ MORE
