  1. 21. Machining of Some Difficult-to-Cut Materials with Rotary Cutting Tools

    Författare :Tero Stjernstoft; KTH; []
    Nyckelord :Difficult-to-Cut material; Metal Matrix Composite MMC ; Machining; Machinability; Rotary Cutting Tool; Acoustic Emission;

    Sammanfattning : Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. LÄS MER

  3. 22. Phase stability and defect structures in (Ti,Al)N hard coatings

    Författare :Katherine M. Calamba; Magnus Odén; Jean Pierson; Mats Johansson; Gregory Abadias; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This study highlights the role of nitrogen vacancies and defect structures in engineering hard coatings with enhanced phase stability and mechanical properties for high temperature applications. Titanium aluminum nitride (Ti,Al)N based materials in the form of thin coatings has remained as an outstanding choice for protection of metal cutting tools due to its superior oxidation resistance and high-temperature wear resistance.

  5. 24. Microstructural evolution of TiAlN hard coatings at elevated pressures and temperatures

    Författare :Niklas Norrby; Magnus Odén; Mats Johansson; Jean-François Pierson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A typical hard coating on metal cutting inserts used in for example turning, milling or drilling operations is TiAlN. At elevated temperatures, TiAlN exhibits a well characterized spinodal decomposition into coherent cubic TiN and AlN rich domains, which is followed by a transformation from cubic to hexagonal AlN.

  7. 25. Characterization of White Layers induced by Hard Turning of AISI 52100 Steel

    Författare :Seyed Hosseini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layer; hard turning; IR-pyrometer; nano-sized grains; martensite; cutting temperature; bainite; cubic boron nitride; residual stress; retained austenite; cutting forces;

    Sammanfattning : Hard turning is a machining process applied to metallic materials with hardness above 45 HRC. The process offers high production flexibility and sustainable manufacturing since it allows performing both rough and finishing machining of complex geometries in one single setup. LÄS MER
