3D Atom Probe, Aluminum alloys |
|
The mechanical properties of grain boundaries in aluminium alloys appear to be very strongly affected by subtle changes in the local chemistry. Due to these microstructural features being on the nanometre scale they are at the limit of conventional TEM based analysis techniques. X-ray and atom probe microanalysis techniques have been applied to the study of grain boundary chemistry in a commercial aluminium alloy. A variety of heat treatments resulting in different stress corrosion cracking susceptibilities have been invesigated. This paper compares typical analyses from one heat treatment to show that the combination of these two techniques with their quite different intrinsic advantages and limitations allows clearer characterisation of the variations in grain boundary chemistry. |

Field Emission |
|
An expression for the critical emission current density at which the superconducting-to-normal state transition occurs in the cathode subsurface region has been obtained. The case at issue is weak emission when the superconductivity can be strengthened due to the increase in electron density in the cathode for penetration of the external electric field into the cathode. |

A brief summary of the major results of Cornell work on the primary state of radiation damage in ion-irradiated tungsten and plantinum is presented. The primary research tool for this research is the field-ion microscope (FIM). The FIM is ideally suited for this research because of its excellent atomic resolution and the ability to examine the interior of the specimens as a result of the field-evaporation effect. This paper summarizes, in outline form: (1) the main experimental programs; (2) the principal experimental quantities determined from the analyses performed on all the individual depleted zones (DZs) observed; (3) a number of the more important results and conclusions concerning the vacancy structure of DZs; and (4) the three-dimensional spatial distribution of self-interstitial atoms detected around DZs in tungsten which had been irradiated and examined in situ at <10 K. |
