  1. 1. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    University essay from KTH/Materialvetenskap

    Author : Filip Ivarsson; [2022]
    Keywords : Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Abstract : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

  2. 2. Electrochemical corrosion analysis of nickel-based superalloys

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Robin Gonzalez; [2022]
    Keywords : Electrochemistry; corrosion; nickel; polarization; EIS; Elektrokemi; korrosion; nickel; polarisation; EIS;

    Abstract : Elektrokemisk korrosionsanalys av legeringar är en essentiell del av den större materialanalysen som måste utföras när en legerings lämplighet för en viss applikation evalueras. Nickelbaserade legeringar är kända för sin utmärkta korrosionsresistans, och de Ni-Cr-Mo-baserade legeringarna 59, 625, och 718 är också så kallade superlegeringar. READ MORE

  3. 3. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach

    University essay from KTH/Materialvetenskap

    Author : Ricardo Rodríguez; [2022]
    Keywords : ;

    Abstract : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. READ MORE

  4. 4. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

    University essay from KTH/Materialvetenskap

    Author : Doom Eleanor Ihensekhien; [2022]
    Keywords : Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Abstract : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. READ MORE

  5. 5. Effect of the Textured Surface on Friction Coefficient

    University essay from KTH/Industriell produktion

    Author : Miguel Angel Valdivieso Muñoz; [2022]
    Keywords : Surface texture; friction coefficient; pin-on-disk; crosspatched; circumferential; Yttextur; friktionskoefficient; pin-on-disk; korspatchad; periferiell;

    Abstract : Friction continues to be one of the main causes of energy loss in mechanical systems despite the advances in technology. As a result, this not only involves energy overuse but also maintains high levels of CO2 emissions that cannot be assumed if society wishes to shift towards a more sustainable industry. READ MORE
