Wiki for uploading microstructural and fractographic images of materials.

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!
