  1. 16. Microstructure Evolution and Mechanical Properties of Haynes 282

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Ceena Joseph; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER

  3. 18. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Eric Tam; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Rockwell-C adhesion test; X-ray diffractrometry XRD ; Pretorius’ effective heat of formation EHF model; Ion-beam sputter deposition IBSD ; Reciprocating sliding wear test; Corrosion; Stainless steels; Thin films; Tribology; Transition metal silicides; X-ray photoelectron spectroscopy XPS ; Potentiodynamic polarisation measurements;

    Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER

  4. 19. Drying and thermal modification of wood - studies on influence of sample size, batch size, and climate on wood response

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Björn Källander; Luleå tekniska universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Research on wood drying and wood modification is primarily done in laboratories, using clear wood specimens treated under well-defined conditions in laboratory cabinets. Laboratory tests differ from industrial treatment both regarding the size and homogeneity of the material treated, and the size of the batch and kiln used. LÄS MER

  5. 20. Simulation of manufacturing processes in product development

    Detta är en avhandling från Luleå tekniska universitet

    Författare :Peter Åström; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : In the manufacture of aero engine components, three key manufacturing processes can be identified. These are welding, heat treatment and mechanical cutting. Depending on what is required in terms of mechanical- and geometrical properties in the final product these processes are typically combined in a certain sequence. LÄS MER
