QUESTION 33 Some steel components require a hard surface but a ductile core. Which of these processes would you recommend to make such a part? O gas carburization age hardening annealing tempering QUESTION 34 Two tensile specimens (A and B) are tested to failure Examination of the failed specimens shows that specimen A had a greater reduction in area than specimen B Based on this observation, you can conclude A. specimen A is tougher than specimen B. B. specimen A is more fatigue resistant than specimen B. C. specimen A is more ductile than specimen B. D. specimen A is more rigid than specimen B.

Solution

33.Gas carburizing in which surface hardening is done

34.SpecimenA more ductile.
