Call for participation
WiKiMicroGraphia will announce prizes for the best uploaded micrographs under student category. Prizes will be given during the student conference "Behind the Teachers Desk (BTTD-13)" in March 2013 at CSIR-National Metallurgical Laboratory, Jamshedpur, India.
Participants of metallography contest of IIM-ATM may upload images in this site. Best microstructure will receive prizes in general category.
Hurry! Start uploading Micrographs to share with the world!
G-X 12 CrMoVWNbN 1011 (G-911)
The formation of Laves phase and its effect in aged G-911 steel for ultra super critical steam cycle boilers.
Material (Name/Designation/Grade):
G-X 12 CrMoVWNbN 1011 (G-911) Material Condition (Heat treatment/Service history/Source):
Normalised at 1053 K for 8 h, hardening by forced air cooling after soaking at 1363 K for 8 h, further, tempering at 1003 K for 8 h followed by air cooling. Stress relieving at 1003 K for 8 h by furnace cooling to 523 K . Ageing heat treatment: at 923 K for 1200 h and then upgraded to 973 K for 300 h.( this ageing treatment simulates to the service ageing at 873 K for 100,000 h) Device:
SEM / Light optical Microscope
