a) What is the "dislocation in metallic alloy? Explain your answer using a diagram. OO OMO OX b) What is the "Step" in metallic alloy? Explain your answer using a diagram. Explain how the annealing process can increase the ductility in metallic alloy. d) A composite material is formed from matrix 70% and fibres 30% . A 10 kN force is applied in the same direction of the fibres. The Young of the fibre is 50 GPa and 8 GPa for the matrix. The composite cross-section area is 200mm2 and the strain is 4 x 10-3. Modulus Calculate: The total modulus of the composite. 1) 2) The force in the fibres. 3) The normal stress on the matrix phase
