  1. 6. P-T evolotion and High-temperature deformation of Precambrian eclogite, Sveconorwegian orogen

    Författare :Lorraine Tual; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eclogite; Precambrian; P–T path; Basal shear zone; Sveconorwegian orogen; Deformation; thermometry;

    Sammanfattning : The 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). LÄS MER

  3. 7. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    Författare :Mathias Agmell; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

    Sammanfattning : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. LÄS MER

  4. 8. Plastic Deformation of Duplex Stainless Steel

    Författare :Magnus Nyström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Sammanfattning : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. LÄS MER

  5. 9. The Precipitation and Deformation Behaviour of Superaustenitic Stainless Steel

    Författare :Stefan Heino; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precipitation; low cycle fatigue TEM; slip behaviour; superaustenitic stainless steel; EDS; cyclic deformation; HAZ; tungsten; molybdenum;

    Sammanfattning : The present study concerns the precipitation behaviour and the deformation characteristics of a superaustenitic stainless steel with composition Fe-24Cr-22Ni-7.3Mo-0.5N (wt%). Regarding precipitation, also materials with Mo partially replaced by W have been studied. LÄS MER

  7. 10. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Författare :Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. LÄS MER
