What is the linear density of a body centered cubic (BCC) unit cell along the cube edges? What is the linear density of a simple cubic (SC) unit cell along the face diagonals? What is the linear density of a face centered cubic (FCC) unit cell along the body diagonal?
(a) Differentiate between Face- Centered Cubic (FCC) and Body-Centered Cubic (BCC) crystal structures. Why FCC metals are more ductile than BCC metals? 5 marks) (ii) show the relationship between the unit cell edge length, a, and the atomic radius, R, for a BCC crystal. Iron has a BCC crystal structure, an atomic radius of 0.124 nm, and atomic weight of 55.85 g/mol. Calculate its theoretical density Given: Avogardo's Number is 6.02 x 105 atoms/mol (5 marks) Figure 1 Determine the...

Calculate (a) LD for FCC Al and (b) for BCC Cr Problem 4 on Linear density of atoms (LD) LD along a certain direction vector of a crystal is defined as LDZ= number of atoms centered along the x direction vector length of the x direction vector For example, along 100 direction of a cubic crystal Linear density is defined as LD 100 = 1 number of atoms centered on [100] direction vector length of [100] direction vector Similarly LD...
Metals with body‑centered cubic (bcc) structures, such as tantalum, are not closely packed. If they were to change to a cubic close‑packed (ccp) structure (under pressure, for instance), their densities would be greater. What would the density of tantalum be if its structure were ccp rather than bcc? Its actual density is 16.7 g⋅cm−316.7 g⋅cm−3 .
Rank the crystal lattice structures in order of decreasingefficiency of space in the structure. 1.Simple cubic 2.Body centered cubic 3.Face centered cubic 4.Hexegonal close packed I know simple cubic is the least effcient, and i figured itwhould be HCP-FCC-BCC-Simple cubic, but its not.. help please!! thanks
