E45 HW08 Due October 29, 2010 Reference: J.F. Shackelford, Introduction to Materials Science for Engineers, 6 th Edition, Prentice Hall, New Jersey (2005) VanAken, Dave. Engineering Concepts: Relationship Between Hardness and Strength. 2001. http://www.industrialheating.com/Articles/Column/62966f835cbb7010VgnVCM100000f932a8c0____ Problem 1 8.1 Which of the alloys in Table 8.1 would you expect to exhibit ductile-to-brittle transition behavior? (State the basis of your selection.) SOLUTION I would expect any BCC alloys to exhibit ductile-to-brittle transition behavior due to BCC having a high number of slip planes. (Shackelford, p. 273) BCC alloys include those with constituent metals such as α- Fe, V, Cr, Mo, and W. (Shackelford, p. 69) Therefore I expect the following to exhibit ductile-to-brittle transition behavior: a. Alloys containing α-Fe, such as steel (1040 carbon steel, 410 stainless steel, L2 tool steel, Ferrous superalloy (410)), with the exception of Ductile iron, since it has been quenched. b.
