    Sammanfattning : Stainless steels were first developed in the early 20th century and have since then emerged as a very diverse class of engineering materials. Along with steels having new combinations of properties, there is a continuous development of new technologies allowing the material to be produced in a faster and more energy effcient manner.

  4. 3. Microstructure of Cermets

    Författare :Per Lindahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermodynamic; microchemistry; N ; AP-FIM; Ti C; cutting tools; SEM; cemented carbide; TEM; sintering;

    Sammanfattning : The microstructure of several TiC-TiN-Mo2C-WC-Co/Ni model alloys and a commercial (Ti,Ta,W,Mo)(C,N)-(Co,Ni) type cermet was studied using x-ray diffraction, optical microscopy, scanning electron microscopy, analytical electron microscopy and atom probe field ion microscopy. In addition thermodynamical calculations were made in order to understand the development of the microstructure during sintering. LÄS MER

  5. 4. Microstructure and Texture of Additive Manufactured Ti-6Al-4V

    Författare :Magnus Neikter; Marta-Lena Antti; Johan Moverare; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; microstructure; Ti-6Al-4V; texture; Material Mechanics; Materialmekanik;

    Sammanfattning : Additive manufacturing (AM) for metals is a manufacturing process that has increased a lot in popularity last few years as it has experienced significant improvements since its beginning, both when it comes to accuracy and deposition rates. There are many different AM processes where the energy sources and deposition methods varies. LÄS MER

  7. 5. The Microstructure of Metal Oxide Additive Silicon Nitride Ceramics
