Question 1: Q 1A: What is Short Range Order (SRO) and Long-Range Order (LRO), give one example for each? (3) Q 1B: Name and give brief details about different quantum number. (3) Q1C: Calculate the atomic radius in “em” for the FCC metal with lattice parameter = 0.5 nm. (3) Q ID: Estimate the concentration of the vacancies in copper at temperature of 25°C. What is the temperature requiring carrying out heat treatment for the copper such that the concentration vacancies produced will be 1500 times more than the equilibrium concentration of vacancies at room temperature? Assume that 18965 cal are required to produce a mole of vacancies in copper. (Copper is FCC structure, with lattice parameter 0.3615 nm) (8) Q1E: A single crystal on Ni has a critical shear stress of 4.7 MPa. If the stress of 12.5 MPa is applied along [001] direction of the unit cell, then what will be the resolved shear stress for the (111)[017] slip system. (8)
