• Vacancy is a line defect and dislocation is a point defect, they are both a defect and there is no difference between them, vacancy is equal to grain boundary but dislocation is not What is the main difference between a vacancy and a dislocation in crystal structures?
• Face centered cubic, BBody centered cubic, Simple cubic Which unit cell has the highest value of Atomic Packing Factor (APF or C.F.)?
• Plastic deformation is permanent but elastic is not, There is no difference between them, Plastic deformation is for plastic materials but elastic deformation is for all materials, Elastic deformation is permanent but plastic is not What is the difference between plastic and elastic deformation?
• Dislocations facilitate plastic deformation of metals, Dislocations make the atoms move slower in the metal, Dislocations move when the elastic deformation occures, Dislocations facilitate elastic deformation of metals What is the role of dislocation in deformation of metals?
