FCC : (h k l) must all be either odd or even

BCC : sum h + k + l must be even.

(Otherwise, an in between plane will cancel the reflection)

What is crystals in science terms?

Crystals are those substances which possess Atoms arranged in a reagular manner.They can be either BCC, FCC or SC.


What is the radius ratio of SC and Bcc and FCC?

Radius ratio of FCC is 1.0 and of BCC is 0.732


Why FCC metals are more ductile than Bcc metals?

FCC has a higher packing efficiency and the slip planes are more closely packed than BCC. Infact BCC has more slip systems than FCC. But they are not as closely packed as FCC. For plastic deformation, we need atleast 5 independent slip systems. Both FCC and BCC have those. But the previously mentioned factor makes FCC more ductile than BCC.


Which is more efficient body centered cubic or face centered cubic?

They are two of the cubic structures for crystals with atoms linked by ionic or covalent bonds. They are also known as BCC and FCC. Table salt, NaCl, and Silicon, for example, assume a FCC structure. For illustrations, please go to the related link.


What is the structure of minerals?

There are a lot of structures existing, the two most common is a body centered crystals (BCC) and face centered crystals (FCC). These crystals sits together and build up grains, grains contains the same type of structures.


What is the Kurdjumov Sachs orientation relationship?

•The Kurdjumov-Sachs (KS) relationship is specified as {110}bcc/{111}fcc, <111>bcc//<101>fcc. •These two differ by only a 5.6° rotation in the interface plane.


Why carbon is more in FCC iron when compared to BC iron even though FCC iron structure has less void space?

In FCC iron, carbon atoms can occupy octahedral sites, contributing to solid solubility. BC iron has fewer octahedral sites available for carbon, limiting solid solubility. Therefore, more carbon can be accommodated in FCC iron despite having a smaller void space.


What are the three differences packing arrangements found in metallic crystals?

Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), Li is an example of bcc , hexagonal close packed (hcp) Au is an example of hcp, or cubic close packed (ccp, also called face centered cubic, fcc) Ag is an example of fcg. The yield strength of a "perfect" single crystal of pure Al is ca. 10^6 psi.


Describe Burger vector in fcc material?

Slip in FCC (face centered cubic) crystals occurs along the close packed plane. Specifically, the slip plane is of type {111}, and the direction is of type . In the diagram, the specific plane and direction are (111) and [-110], respectively. Given the permutations of the slip plane types and direction types, FCC crystals have 12 slip systems. In the FCC lattice, the Burgers vector, b, can be calculated using the following equation:[1] : [1] Where a is the lattice constant of the unit cell. Unit Cell of an FCC material.


How do you calculate density of compounds?

p = n x Mr / Vc x NAwhere n is the atoms/unit cell e.g. fcc packing n = 4 and for bcc packing n = 2Mr is the Atomic Mass in g/molVc is the volume/unit cell cm3 = a3 where a can be found by the radius of the atom and the packing used. e.g in bcc packing it is "a = 4r/1.732" . In Fcc packing it is "a= sin (4r)" or "a = cos (4r)"NA is avorgados constant, = 6.023 x1023

What is the significance of the structure factor for face-centered cubic (FCC) crystals?

The structure factor for face-centered cubic (FCC) crystals is significant because it helps determine the arrangement of atoms in the crystal lattice. It provides information about the symmetry and spacing of atoms in the crystal structure, which is important for understanding the physical and chemical properties of the material.
