3. 2. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

   University essay from KTH/Hållfasthetslära

   Author : Alfred Norberg; [2023]
   Keywords : Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

   Abstract : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. READ MORE

4. 3. Investigation of high temperature stability of additive manufactured austenitic stainless steels for space applications

   University essay from Luleå tekniska universitet/Materialvetenskap

   Author : Belén Alonso Rancurel; [2023]
   Keywords : austenitic stainless steel; additive manufacturing; high temperature corrosion; high temperature stability;

   Abstract : Additive manufacturing (AM) techniques are being studied for their application in the aerospace industry. Numerous benefits come from the already in shape final piece, which needs reduced amount of prime material for its production and can have its shape numerically optimized for weight reduction.

5. 4. Erosion Behaviour of Thermal Barrier Coatings

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Caroline Wännman; [2021]
   Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

   Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE

6. 5. Low temperature embrittlement of duplex stainless steels : A study of alloying elements’ effect

   University essay from KTH/Materialvetenskap

   Author : Libang Lai; [2020]
   Keywords : Duplex stainless steels; low temperature embrittlement; phase separation; alloying element; vanadium addition; mechanical properties; Rostfria duplexstål; sprödhet vid låg temperatur; fasseparering; legeringselement; tillsats av vanadin; mekaniska egenskaper;

   Abstract : Duplex stainless steels (DSSs), consisting of an equal amount of ferrite and austenite phases, have wide applications in e.g. vehicles, chemical engineering as well as nuclear plant  because  of  the  combination  of  excellent  mechanical properties  and  corrosion resistance.
