... transparent and also easily qualify. Metals, however, must be very thin for these optical methods to be applicable. The intensity change upon reflection for very thin films is quite small. On the other hand, the phase shift differences are significant. For this reason, ellipsometry is one of the most...

..., for example, linewidth and Knight shift, may change in a measurable way when the alloy changes phase. The NMR parameter then provides a signature by which to identify each phase. Second, in a two-phase mixture, two NMR signals may be observed. In such a case, quantitative information on the integrated...

The interference directly reflects the net phase shift of the backscattered electron near the central excited atom, which is largely proportional to the product of the electron momentum k and the distance traversed by the electron. The type of central absorbing atom and backscattering neighboring atoms...

... of example, RCo5 (where “R” is a rare-earth element such as samarium, yttrium, lanthanum, cerium, or praseodymium) may shift to a mixture of several compounds or phases. The spraying of α-alumina results in γ-alumina coatings. Heating the deposit to >1000 °C (1830 °F) causes the γ-alumina to revert...

Another important factor in alloys containing a eutectic is the shifting of the coupled zone at elevated solidification speed. The alloy composition where fully eutectic microstructures can be found may shift...
