is interplanar spacing or interatomic spacing directly proportional to grain size?
What are your thoughts? Although this may not be homework, for homework-type questions we need to see your attempt at figuring things out yourself before giving comments.
Before posting your question please supply more information..
for e.g., what material, i mean polycrystalline or single crystal, etc.
So people here would clarify your doubts.
To me, there is no direct relation between particle size, gran size and spacing.
is polycrystalline that i am interested. from debye-scherrer formula where D = k(lamda)/(FWHM)(costheta). i wan to connect spacing and grain size. is it possible? i thought spacing is directly proportional to grain size.
Hi i am sure about the result but it will be helpful.
we know the following three formula:
From these three formulae you arrive at the following two formulae:
[tex]\theta[/tex] and [tex]\beta[/tex] are in degrees and radians, respectively.
This is how i related particle size and 'd' spacing.
thanks a lot.
