Tungsten is a BCC metal with a lattice parameter of 0.3165 nm. What is the direction and magnitude of the Burger’s vector in tungsten, corresponding to the plane and direction of maximum packing density?
What will be an ideal response?
The most closely packed direction in tungsten is [111]. In a body centered cubic crystal, the nearest lattice point to the 0,0,0 lattice point with all positive coordinates is the body centered position at ½, ½, ½ . The vector from the origin to this position is
