  2. 2. Support for re-use of manufacturing experience in product development : from an aerospace perspective

    Författare :Petter Andersson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development;

    Sammanfattning : Globalization, public environmental concern and government legislation are challenging the Swedish industry to be more efficient and increase its efforts in research and in the development of methods and tools for product development and production. Furthermore, the manufacturing industry is changing from producing solely hardware products towards the inclusion of services or soft offers to add more value for the customer. LÄS MER

  3. 3. Effect of boron and hydrogen on microstructure and mechanical properties of cast Ti-6Al-4V

    Författare :Raghuveer Gaddam; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloy; Metallography; Fractography; Castings; Low cycle fatigue; Hydrogen; Boron; Materials science - Construction materials; Teknisk materialvetenskap - Konstruktionsmaterial; Engineering Materials; Materialteknik;

    Sammanfattning : Titanium and its alloys are widely used in applications ranging from aeroengines and offshore equipment to biomedical implants and sporting goods, owing to their high ratio of strength to density, excellent corrosion resistance, and biomedical compatibility. Among the titanium alloys used in aerospace, Ti-6Al-4V (an α+β alloy) is the most widely used, in applications in which the temperature may reach 350°C, at which point it retains good fatigue and fracture properties as well as moderate tensile strength and ductility.

  4. 4. Contributions to multivariate process capability indices

    Författare :Ingrid Tano; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Matematisk statistik inriktning industriell statistik; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik; Matemathical Statistics; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The work presented in this thesis considers multivariate process capability indices (MPCIs) with focus on confidence intervals and tests for MPCIs. It also includes a case study, where multivariate statistical analysis and MPCIs are applied to data from a thermal spraying process at Volvo Aero Corporation. LÄS MER

  5. 5. Skogsarbetets humanisering och rationalisering från 1900 och framåt

    Författare :Bengt Ager; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : Rapporten belyser skogsarbetets förändring i storskogsbruket under perioden 1900 – 2013 under inflytande av rationalisering och humanisering som förändringsprocesser. Utgångsläget var ett ytterst slitsamt, riskabelt och lågbetalt säsongsarbete i kyla och snö, med bortaliggning i undermåliga kojor. LÄS MER
