  2. 6. Surface integrity and corrosion behavior of stainless steels after grinding operations

    Author : Nian Zhou; Rachell Pettersson; Ru Lin Peng; Stuart Lyon; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; stress corrosion cracking; surface integrity; grinding; residual stress; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Abstract : Stainless steels are widely used in applications where both the mechanical properties of steels and high corrosion resistance are required. There is continuous research to enable stainless steel components to be produced in a more economical way and be used in more harsh environments. READ MORE

  4. 7. Strain-assisted corrosion cracking and growth rate inhibitors

    Author : Andrey P Jivkov; Mekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; materialteknik; Mechanical engineering; Material technology; Materiallära; Stress intensity factor; Inhomogeneous materials; Crack evolution; Stress corrosion cracking; Moving boundary; hydraulics;

    Abstract : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. READ MORE

  5. 8. Corrosion testing of heat exchanger tubing

    Author : Ulf Kivisäkk; KTH; []
    Keywords : corrosion testing; heat exchanger; stainless steels; general corrosion; immersion testing; activation; stress corrosion cracking; constant load; u-bends; relaxation; dewpoint corrosion;

    Abstract : Heat exchanger tubes are commonly made from stainless steel.In a heat exchanger both the process fluid and the cooling orheating media can be corrosive. It is therefore important to beable to select materials that do not suffer from corrosion.Current methods in this area, however, suffer from limitationsand shortcomings. READ MORE

  6. 9. Influence of grinding operations on surface integrity and chloride induced stress corrosion cracking of stainless steels

    Author : Nian Zhou; Rachel Pettersson; Ru Lin Peng; Clara Anghel; Per-Lennart Osk Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry; Steel Forming and Surface Engineering;

    Abstract : Stainless steels were developed in the early 20th century and are used where both the mechanical properties of steels and corrosion resistance are required. There is continuous research to allow stainless steel components to be produced in a more economical way and be used in more harsh environments. READ MORE

  7. 10. 2D hybrid modeling of defects in an ultrasonic inspection situation

    Author : Maria Semenova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasonics; T matrix; Finite element method; Scattering; Modelling;

    Abstract : Advanced methods of nondestructive evaluations (NDE) are widely used for in-service inspection in many industrial applications, e.g. nuclear and aerospace industries. In these applications the components are exposed to different degradation mechanisms (e. READ MORE
