(a) What is heat treatment? (b) Explain in details the process to produce martensite structure. (C) (d) Differentiate between annealing and normalizing. Sketch the interdiffusion and self diffusion process. (e) The diffusivity, D for the diffusion of carbon in y iron (FCC) at 927C is 1.32 x 10-11 m/s. If temperature-independent is 2.0 x 10-5 m/s, and the gas constant is 8.314 J/mol.K, calculate the activation energy for diffusion. (2 marks) (6 marks) (4 marks) (4 marks) preexponential (4 marks)
