  1. 26. All-Oxide Ceramic Matrix Composites : Thermal Stability during Tribological Interactions with Superalloys

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Daniel Vazquez Calnacasco; [2021]
    Keywords : Ceramic Matrix Composites; All-Oxide Ceramic Matrix Composites OCMC ; Oxide-Oxide Ceramic Matrix Composites Ox-Ox CMC Ox Ox CMC ; Continuous-Fiber Ceramic Composites CFCC ; Long Fiber Composites LFC ; Ceramic Fiber-Matrix Composites CFMC ; Fiber Reinforced Ceramics FRC ; Superalloys; Inconel 718; Tribology; Elevated Temperature; Alumina; Aluminosilicate; Materiales Compuestos de Matriz Cerámica; Compuestos de Matriz Cerámica base Óxido; Superaleaciones; Inconel 718; Tribología; Alta Temperatura; Alumina; Aluminosilicatos;

    Abstract : The challenges faced in today’s industry require materials capable of working in chemically aggressive environments at elevated temperature, which has fueled the development of oxidation resistant materials. All-Oxide Ceramic Matrix Composites (OCMC) are a promising material family due to their inherent chemical stability, moderate mechanical properties, and low weight. READ MORE

  3. 27. Active learning of interatomic potentials to investigate thermodynamic and elastic properties of Ti0.5Al0.5N at elevated temperature

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Florian Bock; [2021]
    Keywords : Thin Solid Films; TiAlN; Active Learning; MLIP;

    Abstract : With the immense increase in the computational power available for the material science community in recent years, a range of new discoveries were made possible. Accurate investigations of large scale atomic systems, however, still come with an extremely high computational demand. READ MORE

  4. 28. Lubricants for Hot Stamping of Aluminum: Evaluation of Tribological Behavior and Cleanability

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Barbara Maria Rodriguez Leal; [2021]
    Keywords : Tribology; High-temperature; Metal-forming; Aluminum;

    Abstract : Working at elevated temperature has its challenges due to the high level of complexity whenthe tribosystems operate under harsh conditions, commonly resulting in an increase on thefriction and thermal softening that goes into severe adhesion, severe abrasion and materialtransfer. Despite considerable research, there is a lack of research on tribology applied to hightemperature processes. READ MORE

  5. 29. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE

  6. 30. Effect of experimental warming and assembly history on wood decomposition

    University essay from Mittuniversitetet/Institutionen för naturvetenskap

    Author : Saba Hagos; [2020]
    Keywords : wood decay fungi; species composition; assembly history; warming; temperature; fungal growth; decomposition; carbon dioxide; climate feedbacks; species priority; polypore; microcosm; Norway spruce;

    Abstract : Sammanfattning: Wood decay fungi are the main decomposer of lignocellulose material stored in wood. Thus, all factors that affect them could affect their ecological function. This in return, may affect ecosystem functioning in terms of altered carbon emissions from dead wood. READ MORE
