You are working with a derivative of naphthalene and, like its parent compound, it has a high triple point and sublimates fairly readily at temperatures near room temperature. At temperatures below 400 K, you find that the vapor pressure of its solid can be represented by the function 4200 K T 1 atm Use this equation to estimate the normal sublimation temperature of this compound, Tsubl (in K).

A diffusion couple of two metals, A and B, was fashioned as shown: Diffusion of A atoms A-B alloy B Diffusion of B atoms After a 690 hour heat treatment at 1120°C the concentration of A is 1.8 wt% at the 3.2 mm position within Metal B. At what temperature (in Kelvin) must the diffusion couple need to be heated to produce this same concentration at a 2.3 mm position after 690 h? The preexponential and activation energy values for the diffusion of A in B are 1.9 x 104 m²/s and 239 kJ/mol, respectively.

XB We discussed in lecture how in the early phase of a phase transformation, for example as a ß phase forms in a matrix of an a phase as shown in Fig 1.38(a), the interface between the two phases contributes to the Gibbs free energy of the ß phase. (a) In Figure 1.38(b), the Gibbs free energy curves of the ß phase are shown for a case (1) where the 3 phase is of radius r and (2) for the case where the ß phase has a radius of size. Write an expression for the difference in the Gibbs free energy of the two cases. (b) Notice the Gibbs free energy curve for the a phase on the left side of Figure 1.38(b). What can you say is different about the a phase in equilibrium with the ß phase when the ß phase is (1) of size r versus when the ß phase is (2) of size ∞.
