  1. 1. On the Effect of Grain Size and Hardness on the Machinability of Superalloys and Chip Deformation

    Author : Stefan Olovsjö; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superalloys; Microstructure; Burr; Machinability; Waspaloy; Chip microstructure; Tool wear; Alloy 718;

    Abstract : Superalloys are used in applications such as gas turbines, steam power plants and nuclear power systems that require good high temperature properties and/or exceptional corrosion resistance. Superalloys are classified as materials that are “difficult to machine”. In production machining is a most commonly occurring procedure. READ MORE

  2. 2. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys

    Author : Stefan Olovsjö; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear mechanisms; Simulation; Tool wear; Burr; Meta-modelling; Inconel 718; Metal cutting; Superalloy; Waspaloy; Chip morphology; Notch wear; Alloy 718; JMatPro;

    Abstract : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. READ MORE

  3. 3. Investigations on Reducing Burr Formation in Metal Cutting

    Author : Vijay Sharan; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Metal cutting is a very common operation in the manufacturing industry. Drilling and other hole-making operations perhaps account for 50% of all metal cutting, according to some investigations. All metal cutting including drilling always produces burrs, as a by-product. READ MORE

  4. 4. Machinability variations in alloy 718 turbine components

    Author : Pajazit Avdovic; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variation in tool; hardness; Machining; flank wear; notch wear; alloy 718; grain size; instability; variation in material;

    Abstract : Machinability Variations in Alloy 718 Turbine Components PAJAZIT AVDOVIC Department of Materials and Manufacturing TechnologyChalmers University of Technology AbstractAlloy 718 has a reputation for being very troublesome during the cutting process. It was suspected that this material was too hard and having too fine grain size and that these characteristics caused damage to cutting tools during processing. READ MORE

  5. 5. Measurements in Idiopathic Normal Pressure Hydrocephalus Computerized neuropsychological test battery and intracranial pulse waves

    University dissertation from Umeå : Umeå universitet

    Author : Anders Behrens; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrocephalus; Normal Pressure; Neuropsychological tests; Neuropsychology; Reliability and validity; Software; Dementia; intracranial pressure; spinal puncture; cerebrospinal fluid pressure; pulse pressure waves; Blood flow velocity; Middle cerebral artery; Pulsatility index; neurologi; Neurology;

    Abstract : Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms. READ MORE
