Explain why Bcc fcc and cph lattice packing and features of grain structure affect the ductillity and brittleness of parent metallic materials?
What is FCC FCC means Face Centered Cubic Ductility is the mechanical property of a material.It is the material's ability to deform under the tensile stress without fracture.So it is depends on the atoms how they arranged in a lattice and its grain size. The ability to absorb the energy of the impact and fracture resistance depends on the arrangement of the atoms in a lattice and features of grain structure.
What is the number of atoms per unit cell in cubic closed packing arrangement?
Face Centered Cubic (FCC) crystal structure has 4 atoms contained per unit cell. The relationship of of radius (R) to the lattice parameter (a) is 4R = a(sqrt(2)). In terms of lattice parameter (a)it is equal to, a = 2R(sqrt(2)).
How do you calculate lattice parameter of orthorhombic crystals?
Lattice parameter refers to the physical dimension of unit cells in a crystal lattice. The lattice parameter will need to be calculated differently depending on the lattice structure: Simple cubic, Body-centered cubic, or Face-centered cubic.
Lattice parameter of metal A and B are 2 and 4 what will be lattice parameter of alloy AB A20B and A50B?
Indeterminate. If the atoms form a perfectly mixed solution then you might guess 2a+4b where a and b are the fractions of A and B. But if they form a super-lattice where the stacking of the atoms only repeats over a long range (as happens in the many structures of silicon carbide [silicon and carbon are not metals]) then you can get almost anything, with various seemingly unconnected sequences and lattice lengths, even in different directions. For very dilute things like A50B you will get the normal lattice period of A over much of a crystal but with lattice distortions around the occasional B atom. That would cause a broadening of x-ray diffraction patterns.
What is a three dimensional pattern of atoms and ions in a solid called?
It's a crystal lattice or lattice structure
What is the value of the lattice parameter of iron?
0.286 nm
The lattice parameter of SiC is 4.36 and that of diamond is 3.57 is this difference large or small?
Large. Consider that the lattice parameter for C only changes about 0.2% from 300 to 1000 K.

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 can salt be identified?
- after taste - by chemical analysys - by microscopic examination of the crystals - measuring some physical parameters as refractive index, lattice parameter etc.
