✦ Synopsis

Intermetallics have been studied by means of Atom Probe Field Ion Microscopy. Atom-Probe techniques have been used to determine the phase composition and to study the role and the inΒ―uence of additional elements. The use of the Tomographic Atom Probe makes it possible to map out the distribution of chemical species in a small volume of the material at a near atomic scale. This has been particularly used in order to study segregation of additional elements at interfaces or planar and linear defects in TiAl base and FeAl base alloys.

The electronic mechanisms leading to the formation of excited atoms from ion-bombarded metal surfaces have been examined in light of recent experimental observations. Specifically, populations and kinetic energy distributions are compared for metastable fine structure states of In, Rh, Ni, Co and Ag

Atomic force microscopy was used to examine the crystal growth-induced fine surface features on the {1 0 0} faces of zeolite A. Features reported previously (terraces with ledges $1.2 nm in height, and small pyramidal structures composed of layers with thickness of $1.2 nm) as well as features not r
