Impact specimen geometry on T23 and TP347HFG steels behaviour during steam oxidation at harsh conditions. Corrosion Engineering, Science and Technology, 2017, Vol.52, Iss.1, pp46-531478-422Xhttp://dx.doi.org/10.1080/1478422X.2016.1185568http://dspace.lib.cranfield.ac.uk/handle/1826/10222Ferritic T23 steel and austenitic TP347HFG steel have been studied with an emphasis on understanding the impact of specimen geometry on their steam oxidation behaviour. The selected materials were tested over a wide range of temperatures from 600 to 750°C. The tests were carried out in 100% steam conditions for 1000 hours. The tests indicated that the ‘curved-shaped’ specimens show slower mass gain, scale ticking and void nucleation rates than ‘bridge-shaped’ specimens (with flat and convex surfaces combined). Furthermore, a bridge TP347HFG sample showed the formation of lower amount of flaky oxide at 750°C.enAttribution 4.0 InternationalAttribution 4.0 International (CC BY 4.0) You are free to: Share — copy and redistribute the material in any medium or format, Adapt — remix, transform, and build upon the material for any purpose, even commercially.
