Interstitial Voids in BCC Crystals

[@이수영-r1e]

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

[@kanishksharma1716]

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

[@maddy3829]

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

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🙏

But bbc has 2 atoms in it and so there should be 2 octahedral void and 4 tetrahedral voids according to concept given in book.. but explanation is different..can anybody pls clearify this

[@gaurabroy123]

SO in BCC Td voids are part of Oh voids?

[@rajeshprasad101]

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!!

awesome explanation!

[@shubhabratamaity3674]

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

[@introductiontomaterialsscience]

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']

Good but lengthy

[@tamannaparween7700]

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..

[@rajeshprasadlectures]

The numbers you are quoting don't seem to be right for BCC.

[@sabbusabbu4200]

In bcc unit cell there are 2 atoms in it. And so there should be 2 octahedral and 4 tetrahedral voids in it But above explanation is different..

[@rajeshprasadlectures]

@@sabbusabbu4200 1 octahedral and 2 tetrahedral voids per atom is true for CCP and HCP crystals. It is not true for BCC.

Sir, but there are no tetrahedral voids in bcc

[@darkdevil6187]

Are u sure mate lol

[@MrNiirmal]

He is not ur bro . He is professor please respect that .

[@hemachandrareddy4485]

You have half knowledge that's you said like that

[@physicsrox184]

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.
