Thank you for your lectures (and study materials), professor. You are a true saint. It is not easy to find some coherent content on crystallography and diffraction like this. As a chemist I'm more interested of X-ray diffraction of small organic molecules and metal complexes rather than electron diffraction of inorganic materials. But I guess the basic principles are the same.

You are very welcome.

Thank you Professor for such informative lectures. It is of great help, especially to students new to learning crystallography. Thank you!

Indeed!

[@SFYN..]

Loved the new additions to the slides. It's always wonderful to take those 9 crystallography lectures. ❣️

[@bhadeshia123]

Thank you.

Which other 9 lectures you are talking about?

Hello.. Sir... Love from Pakistan

Hello Dr. Badheshia. For the EBSD picture you show at the 13 minute mark if you had the same surface orientation for all crystals but there were still distinct grains and grain boundaries would it still be considered polycrystalline? In other words all grains have same eg. 100 surface orientation but the direction of (for example) 110 was not the same from 1 grain to the adjacent one how would you classify it (single or polycrystalline)? Very nice lecture!

[@bhadeshia123]

Yes, as long as the grains are not in precisely the same orientation, they are different grains and the material is polycrystalline.

Great lecture, tks from Br

You are welcome! There is a considerable amount of free teaching materials and books available from www.phase-trans.msm.cam.ac.uk

[@akeedasharma4249]

Hello sir, can you present lectures on indexing of Electrons Diffraction spots (SAED)?

[@bhadeshia123]

Lecture 6 will deal with that.
