1. Please state if the claims that are listed below are True (T) or False (F). pis jer ettert, PUS PRODI i) ii) iii) iv) v) vi) vii) viii) ix) X) For the construction of phase diagrams, instantaneous quench to a fixed temperature is assumed. The presence of vacancies in a crystal increases the entropy of the crystal. For the movement of dislocations, the combination of the slip plane and the slip direction is called a slip system. The preferred slip systems are the ones where the atomic distortion that accompanies the motion of dislocation is minimum. Grain size of alloys can be controlled by the rate of solidification from the liquid phase. The critical free energy for nucleation is higher for heterogeneous nucleation than homogeneous nucleation. A single crystal only has low-angle grain boundaries. Diffusion is faster inside the grains compared to the grain boundaries. It is easier for interstitial atoms to diffuse in an FCC lattice compared to a BCC lattice. In an FCC lattice that…
