1. In a diffusion process called "carburization", a-Fe steel is exposed to carbon gas. We (20) a. What time is required to nitride a 0.002% steel, to obtain 0.12% Cat a distance of 0.005 inches beneath the surface at 675°C? The carbon concentration at the surface = 0.15%. b. How will the time required in Part (a) change if the "carburization process was done on y-Fe steel and why? Note: No calculation necessary. This is a qualitative problem c. How will the time required in Part (a) change if the "carburization" process was done at 575°C and why? Note: No calculation necessary. This is a qualitative problem
