The solid inner core represents only —5% of the core s mass and —4% of its volume. Geophysical models of the inner core have identified its structure, elastic properties, and modeled its crystallization history. This, without question, is the most remote region of the planet...

To calculate cavitation in a macroscopic specimen, one must determine the concentration and crystallization history of each volume element in the sample during the sorptloii process and apply Equation 6 to each from the time saturation occurs. This has been done for films by solving a non-Ficklan transport equation, an equation for local crystallization and Equation 6 simultaneously. The transport and crystallization equations (without their initial and boundary conditions) are...

Where X(f) and X are the crystallized volume fraction at time t and in equilibrium conditions, respectively. For simplicity and for the sake of generalization X is here assumed to be a material constant, although it has been reported its dependence upon the crystallization history (crystal size distribution and degree of perfection, Ziabicki, 1976).

A similar analysis of a melt-crystallized poly(ethylene terephthalate), PET, of the typical molecular mass of a polyester showed a surprising reversing melting peak, as seen in Fig. 3.92. On comparison with an amorphous PET, one finds that the reversing peak depends on crystallization history, as is shown in Fig. 4.136. The change of the glass transition with crystallization is typical for polymers. It shows a...

The Messo Oslo-type crystallizer reached runtimes of around 3 weeks between washouts without any disturbance from scaling. This was a breakthrough in the Oslo crystallizer history for salt crystallization and the approved consequence of the inversion of the internal recirculation. The process required about 11 t/h of heating steam and evaporated 34 t of water per houn... 

Nonetheless, MC-ICP-MS has been used successfully for Nd isotopic analysis in cosmochemistry. A good example is the combined use of the Sm-Nd and Lu-Hf systems by Blichert-Toft et al. [70], They analyzed 18 eucrites (Table 10.1) and found an Sm— " Nd age of 4464 + 75 Ma, with three cumulative eucrites defining a better constrained isochron of 4470 + 22 Ma. This suggests that cumulative eucrites have a crystallization age that postdates the formation of the solar system by about 100 Ma and implies a fairly protracted crystallization history for the eucrite parent body, which is thought to be the asteroid 4 Vesta (Table 10.1). Combined " Nd and Nd ages of eucrites [71, 72] give a some-...
