Dear Prof. , I think, in the slide at 18:17 , the (110) plane should be parallel to the Z axis, but it's parallel to the x axis, so it is the (011) plane.

The plane is indeed (011) but there is no mistake. I am using the standard crystallographic notation that [uvw] in square brackets refers to directions, not planes.

@@bhadeshia123 Thanks for the info! I'm still a little confused that when finding poles for {110} plane, it must lies on great circle containing (100) and (001) pole. Is this great circle the trace of 110 plane?

Thank you for your detailed description, sir! I think this video is really helpful to many MSE students. However, I didn't understand one thing, so I want to ask a question. At 9:13, you said that the pole (the black dot in fig. (d)) will be at 90 degrees to every point of the trace. I didn't understand why the point is vertical to the trace line. I understand that the pole of [011] is perpendicular to the plane (011), but why is it perpendicular to the trace on the equatorial plane?

If you look at the three-dimensional diagram, bottom right, the pole goes from the centre of the sphere and towards the right (i.e., normal to (011) and therefore is at 90° from all points on the plane. Note that the plane is inclined to the equatorial plane.

​@@bhadeshia123 Ah, you mean the plane (011) has the "real" line, and the trace is just the projection of the "real" line..? So, even though the trace is on the equatorial plane, pole of [011] is perpendicular to the line overlapping plane (011) and the Northern Hemisphere. I hope I understand your description, sir. Thank you for your quick answer, and I hope you have a great day!

Hello Dr. Bhadeshia. At the 19:29 mark a pole is marked as one, one bar, one bar on the top left quadrant. Should it not be one bar, one bar, one instead? Thx.

@bhadeshia123 7 ай бұрын
Thank you, you are quite right, it should read bar 1, bar 1, 1, as shown on page 40 of this book that you can download free-of-charge. www.phase-trans.msm.cam.ac.uk/2020/Crystallography_book.pdf

why do we have (111) trace plane (31:56) different from the (111) trace plane in 19:08 I still confuse with the meteorite sample actually Prof. Please give me any clue or more explanation. thank you before
@bhadeshia123
@bhadeshia123 4 жыл бұрын
The trace at 19.08 is not of (111) but of (0-1 1). You have to be specific about the meteorite question.
