... facilitates an elongated grain orientation, which exhibits enhanced impact strength, high temperature creep and fatigue resistance, and improved corrosion resistance compared with off-axis orientations. Of concern to turbine designers are the effects of cyclic fatigue, thermal gradients, and potential stress...

...Gang Ma; Xiang Ling Ultrasonic impact treatment (UIT) can be used to create a thin nanostructured surface layer that plays a significant role in enhancing the overall strength, fatigue life, and corrosion resistance of the treated material. The hardness and elastic modulus of surface nanostructured...

...Eelke S. Focke; Arnold M. Gresnigt; Annemiek Hilberink A promising possibility to reduce costs in pipelines that require corrosion resistant alloys (CRAs) is the use of lined pipe, consisting of a carbon steel outer pipe and a CRA liner pipe. Research has been carried out into the local buckling...

...Pierre Mertiny; Kulvinder Juss; Mohab M. El Ghareeb Pressure piping made from fiber-reinforced polymer composites is becoming increasingly popular. This development is driven by the need for lighter and more corrosion resistant components. Compared with traditional metallic structures, composites...

... corrosion resistance of specimens prepared from a welded container were the same as those from flat welded plates. Cyclic polarization of Alloy 22 mockup and archive specimens in 1 M NaCl at 90 ° C Cyclic polarization of Alloy 22 mockup and archive specimens in 5 M...

...Ivan Klevtsov; Harri Tallermo; Tatjana Bojarinova; Roger Crane The high-temperature corrosion resistance of several boiler steels was tested experimentally in laboratory and industrial conditions in the presence of chlorine-containing external deposits. The empirical kinetic equations...

...-crystalline corrosion initiated at or near welding position between head and body of cylinder, electrochemical corrosion due to chloride ions in electrolyte and corrosive action formed by oxygen separator and hydrogen separator. Some measures of corrosion resistance and design improvement were proposed...

.... The applicability of martensitic alloys X10CrMoVNb91 and X20CrMoV121 for superheaters has been examined and empirical equations to predict alloy corrosion resistance have been developed for the operational temperature range. Alloy 10CrMoVNb91 is found highly suitable for superheaters in boilers firing fossil fuels...
