State different types of dislocation with neat sketches .arrow_forwardTin atoms are introduced into an FCC copper crystal, producing an alloy with a lattice parameter of 3.7589 3 10–8 cm and a density of 8.772 g/cm3. Calculate the atomic percentage of tin present in the alloyarrow_forwardIron exhibits an allotropic behavior change of solid state structure in such a way that when it is heated to 910 C it undergoes a structure change from body-centered cubic BCC to face-centered cubic FCC considering that the atomic radius of iron increases to 0.1241 nm or 0.126 nm more when said temperature is reached obtainThe volume change experienced by the structure when the temperature of 910 C is reachedarrow_forward
- A particular element with an atomic mass of 32.5g/mole has an FCC structure and has a density of 2200kg m-3. Estimate the atomic radius of the element from that data. Show all working and include units in your results.arrow_forward10- Iron, Fe, can have two different crystal structure (BCC and FCC). In order to determine the crystal structure, X-ray diffraction was measured and the diffraction pattern of an iron piece is given here. Based on this, calculate the lattice parameter of this sample and determine its crystal structure, knowing that lattice parameter of FCC and BCC iron are 0.35 nm and 0.28 nm, respectively. Hints: Assume n in Bragg's law =1, and wavelength of 0.154 nm.

(b) Determine the volume change accompanied by the transformation of y-Fe (FCC) to a-Fe (BCC) during cooling. Note that the atomic radii for a-Fe, y-Fe, and C are 0.124nm, 0.127mm, and 0.077mm, respectively. (HINT: Because the number of atoms in FCC and BCC differs, consider volume per atom in the calculation of volume change).arrow_forward
