Sir, I have a doubt about the angle, in case of Small angle grain boundary, few literature have used the small angle grain boundary as, less than 15 degree(giving the reference of Hirth, J.P.; Lothe, J. Theory of Dislocations, 2nd ed.; Krieger Publishing Company: Malabar, India, 1982), but in the video you have suggested that is is less than 5 degree, so which is correct ? kindly help, to resolve the confusion !
@pailasaisravan54234 жыл бұрын
sir already said it is rougly less than 5 but that is upto the guy who is publishing paper to define his word of small angle

Is there a way or a technique to calculate the angle of rotation?
@introductiontomaterialsscience4 жыл бұрын
One can find this by diffraction techniques. Now a days it is routinely done by a technique called electron backscatter diffraction (EBSD) using scanning electron microscope (SEM).

Does the amorphous materials having grain boundaries??
@introductiontomaterialsscience4 жыл бұрын
No, amorphous materials do not have any grains or grain boundaries.
@NirmalyaRoy-m2l2 ай бұрын
how can they be ? as grains are present in polycrystalline materials and I don't think amorphous have any thing like that

I have question - interaction between dislocation density and precipitate helps in grain boundary strengthening. How can we explain it
@introductiontomaterialsscience4 жыл бұрын
Three different strengthening mechanisms are involved in your question: 1. strain hardening; interaction of dislocation with other dislocation, 2. precipitation hardening: interaction of dislocations with precipitate, 3. grain boundary hardening: interaction of dislocations with grain boundaries.

15.19 and 17.56 is grain boundary plane actually a curved surface in 3d?

Yes, it is a curved surface.

How do we able to watch all this boundary ?
@introductiontomaterialsscience4 жыл бұрын
One can see then in microscopes. Optical microscopy is good enough. But one can also use scanning or transmission electron microscopy.

Are you trying to say that.. Rotation axis and grain boundary are considered same.. In this case

In tilt boundary you always mentioned about being perpendicular to the grain boundary.. Whereas you wrote it parallel... Didn't get you sir..

The same doubt is here? Sir, can you pls help us in resolving this doubt?
@vikashlamba91215 жыл бұрын
If you see the grain boundary in 2D, it seems that the rotation axis is perpendicular to grain boundary but in the lecture, sir mentioned grain boundary plane not only grain boundary in 2D. Extend the grain boundary in the direction perpendicular to the paper's plane it will become grain boundary plane. so the grain boundary plane and the axis of rotation become parallel.
