Question 3 Diffusion by which mechanism occurs more rapidly in metal alloys? O a. Interstitial diffusion Ob. Vacancy diffusion
It is believed that interstitial diffusion is faster than vacancy diffusion. Can you show this by comparing the values of diffusion coefficients of a pair of cases (one values for each type of diffusion) from Table 5.2......
