Thanks! Couldn't find this great an explanation anywhere!

I am a Korean student. Thank you for leaving such a good lecture for material engineering students.

No one explains better than you sir...become a fan of ur style of teaching, so easily you made me understand this complex topic..😊

Really a cool explanation of tough imagination.. Thankful to you

You have amazing drawings.

Thank you for this amazing and Informative video.

U helped me in my engineering. Thank you.

Dear guardian angel, Happy teacher's day !!! India is blessed with magical teachers like you..May god fulfill all your wishes... Thank you very much sir🙏

Surprising, but true! An OH void in a monatomic BCC crystal consists of four TH voids. Despite this, the atom that can fit in TH void is larger than the atom can fit in the OH void!!

Sir,cant able to understand about distorted tetrahedral..kindly guide

In a regular tetrahedron all six edges are equal in length and all faces are equilateral triangles. In the tetrahedron for BCC the two edges are of length 'a 'and four of 'sqrt[3] a'. The faces are not equilateral but isosceles triangles with two sides of 'sqrt[3] a' and one side of 'a'. In this sense they are distorted, meaning 'not regular'. [edit: Not 'sqrt[3] a' but 'sqrt[3] a/2']

But in book it is given that two octahedral and 4 tetrahedral voids are there in body centred unit cell.. but here the explanation is different..

Hema Chandra Reddy I repeat it again .. There are no REGULAR * TETRAHEDRAL VOIDS in BODY CENTERED CUBIC LATTICE... But the collection of two irregular tetrahedral void is what we see as the octahedral voids. We can explain all the voids saying that there are a total of 6 octahedral voids in a unit cell . Rather than perceiving the same void as collection of two irregular tetrahedral voids we should look at it as one regular octahedral void.
