Sir, can we relate the phase boundaries like coherent and semi-coherent to the grain boundaries

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 !

Is there a way or a technique to calculate the angle of rotation?

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).

No, amorphous materials do not have any grains or grain boundaries.

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
@introductiontomaterialsscience
@introductiontomaterialsscience 4 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.

One can see then in microscopes. Optical microscopy is good enough. But one can also use scanning or transmission electron microscopy.

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

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.
