Which of the following would probably not be a criterion for choosing a material for the manufacture of a very high end (i.e., cost doesn't matter to consumer) cookpot:

a. weldability no welding

b. toxicity high priority

c. corrosion resistance high priority

d. formability high priority

e. tensile strength involved somewhat in formability, and in service stresses

Which of the following is probably the best choice for the manufacture of a very high end (i.e., cost doesn't matter to consumer) cookpot:

a. a beryllium alloy toxic

b. Ti-6-4 now, this is really high end!

c. 1020 steel rusts

d. 304 stainless steel pretty good, but most people have one

Which of the following is probably the best choice for the manufacture of the paper-holding rings in a ring binder notebook:

a. class 35 cast iron brittle, wouldn't cast the rings

b. 304 stainless steel OK...might be a little costly......formable

c. platinum too expensive

d. A2 tool steel why?

e. 1040 steel good, formable, inexpensive, might have a small problem with corrosion (could Ni plate)

The Hume-Rothery rules predict for the solubility of V in alpha-Ti, and beta-Ti:

a. alpha - limited, beta - extensive

b. alpha - extensive, beta - limited

c. alpha - limited, beta - limited

d. alpha - extensive, beta - extensive

Data: Atomic radii

Ti ­ 1.46 Å, V ­ 1.38 Å close enough to get fair amount of solubility....but doesn't differentiate between solubilities in alpha and beta forms

Crystal structures

alpha-Ti ­ close-packed, beta-Ti ­ "bcc", V ­ "bcc"
says V dissolves extensively in beta-Ti; solubility in alpha-Ti is relatively limited
