Abstract

The Stuttgart ultra-high-vacuum (UHV) diffusion bonding facility serves to produce high-quality solid solid model interfaces. An overview is given on the more recent work comprising bicrystals of metal – metal, ceramics– ceramics, and metal – ceramics combinations. Orientation errors below 0.1° have been obtained routinely with sapphire – sapphire bicrystals. The bi- and tricrystals produced serve as samples for mechanical testing and as specimens for both analytical and quantitative high-resolution electron microscopy. The close control of the interface chemistry allows for segregation studies and studies of the influence dopants have on the interface properties. UHV diffusion-bonded low-angle grain boundaries present arrays of edge or screw dislocations of just one type and thus facilitate investigations of these dislocations and their core structures.

Abstract

Die Stuttgarter Diffusionsverschweißanlage dient der Herstellung hochwertiger Modellgrenzflächen in Festkörpern. Neuere Arbeiten an Metall – Metall-, Keramik –Keramik-, und Metall–Keramik-Verbunden werden vorgestellt. Orientierungsfehler kleiner als 0.1° werden für Saphir – Saphir Zweikristalle regelmäßig erreicht. Die hergestellten Zwei-und Dreikristalle dienen als Proben sowohl in Verformungsversuchen als auch für die analytische Elektronenmikroskopie oder quantitative Hochauflösungsmikroskopie. Die Beherrschung der Grenzflächenchemie ermöglicht Untersuchungen des Segregationsverhaltens und des Einflusses, den Fremdatome auf die Grenzflächeneigenschaften haben. UHV-diffusionsverschweißte Kleinwinkelkorngrenzen sind regelmäßige Anordnungen von entweder Stufen- oder Schraubenversetzungen und erleichtern so die Untersuchung solcher Versetzungen und deren Kernstrukturen.

Keywords: Diffusion bonding; Grain boundaries; Sapphire; Strontium titanate; Metal ceramics boundaries
