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!
