Although many similarities exist in the precipitation behavior in ferritic and austenitic steels, the nucleation and growth mechanisms in these systems have eluded full comprehension. However, it is apparent that the initial clustering of substitutional and interstitial atoms can dictate the structure and orientation relationships of subsequent phases. Hence, in order to realize the benefits of these decomposition transformations, a better understanding of the incipient nucleation event is imperative. Therefore, a transmission electron microscopy study of a quenched-aged 18-10 stainless steel doped with 0.3 w/o P was undertaken as part of a more comprehensive research program. The precipitation reactions in this austenitic stainless steel were originally surveyed by Rowcliffe and Nicholson [1] and Rowcliffe and Eyre [2], These investigators observed a variety of defects ranging from vacancy defects on {100} planes at lower aging temperatures to Cr3P laths with {100} habit planes at higher aging temperatures.

This study reportsin situobservations of the formation of the δ′-ZrO phase, occurring during the annealing of transmission electron microscopy (TEM) thin foils of both pure Zr and a Zr–Sn–Nb–Mo alloy at 973 K in a transmission electron microsope. The lattice parameters of δ′-ZrO were measured and determined to be similar to those of the ω-Zr phase. The orientation relationship between the δ′-ZrO and α-Zr phases has been identified as either {(11 \overline{2}0)}_{\rm ZrO}//{(0002)}_{\alpha} and {[0002]}_{\rm ZrO}//{[11 \overline{2}0]}_{\alpha} or {(\overline{1}011)}_{\rm ZrO}//{(0002)}_{\alpha} and {[01{\overline 1}1]_{{\rm{ZrO}}}}//{[11{\overline 2}0]_\alpha} depending on the orientation of the α grain relative to the TEM thin-foil normal. The nucleation and growth of δ′-ZrO were dynamically observed. This study suggests a new and convenient way to study oxidation mechanisms in Zr alloys and provides a deeper understanding of the properties of the newly reported δ′-ZrO. Since δ′-ZrO has a Zr sublattice which is identical to that of ω-Zr, the orientation relationships between the α and δ′-ZrO phases may also shed light on the orientation relations existing between α- and ω-Zr, and hence α- and ω-Ti.

Mgo Substrate

A YNi2B2C thin film deposited on MgO(001) substrate by pulsed laser deposition has been investigated by transmission electron microscopy (TEM). Cross-sectional TEM analyses show that the YNi2B2C film grows in the [001] direction. Y2O3 exists not only as an interlayer at the interface of the YNi2B2C thin film and the MgO substrate but occasionally also in the YNi2B2C thin film near the substrate. The orientation relationships between the YNi2B2C thin film, Y2O3 interlayer, and MgO substrate are determined from electron-diffraction patterns to be MgO(001)[100] ‖ Y2O3(001)[100], YNi2B2C(001)[110] ‖ Y2O3(001)[100] ‖ Y2O3(001)[100, and YNi2B2C(001)[100] ‖ Y2O3(001)[100 1.5‖ Y2O3(001)[100] ‖ Y2O3(001)[100 (the numeral above the “parallel” symbol represents the misorientation (in degrees) between the [100] ‖ Y2O3(001)[100 directions).
