چکیده

FIM atom-probe techniques have been used in order to investigate concentration modulations related to (001) APB's in Cu3 ,Pd. Layer by layer analysis of (001) superstructure planes of a long-period single crystal (20.5 % Pd) exhibits LRO modulations with correlation lengths oscillating between 6 and 7 doO,. The average wavelength (6.5 dO0,) is in good agreement with the mean size of one-dimensional ordered domains, as measured by HRTEM.

FIM-ATOM PROBE INVESTIGATION OF MELT-SPUN PERMANENT MAGNETS BASED ON NdFeB

The microstructure of Nd15Fe7,B8 in the optimum magnetic state is compared to that of overquenched and heat treated specimens using Field Ion Microscopy (FIM) and Atom Probe (AP) techniques. Apart from the hard magnetic Nd2FeI4B ( (P ) and the nonmagnetic Nd,,,Fe4B4 ( 11 ) a metastable Nd7Fe3 phase controls the magnetic properties of melt-spun NdFeB ribbons. Furthermore the influence of a parti...

Localizing of a Four-Level Atom via Absorption Spectrum

We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...

AN ATOM-PROBE ANALYSIS OF Al-Li ALLOYS

The aging process in A1-Li alloys was studied by an atom-probe FIM. Two types of precipitates were recognized in the FIM image, one is brightly imaged with a high degree of order in its structure and the other appeared dark against the Al matrix. Atom-probe analysis showed that the Li concentration is in a range of 10 to 25 at% in the dark precipitate and approximately 25 at% in the bright prec...

A Fim/ap Investigation of a Rapidly Solidified Aluminium-chromium Alloy

A rapidly solidified A1 6 to gwt%Cr alloy formed by vapour deposition has been studied by field-ion microscopy and atom probe microanalysis (FIM/AP). The as-deposited material was found to contain brightly imaging Cr-rich particles, both spherical and rod-shaped, of about 0.5-lnm in diameter and up to 5nm long. Random area AP analysis showed the presence of Cr-enrichment on a very fine scale, w...

Focused ion beam preparation of atom probe specimens containing a single crystallographically well-defined grain boundary.

Needle-shaped atom probe specimens containing a single grain boundary were produced using the focused ion beam (FIB) of a two-beam FIB/SEM (scanning electron microscope) system. The presented specimen preparation approach allows the unprecedented study of a grain boundary which is well characterised in its crystallographic orientation by means of the field ion microscope (FIM) and the tomograph...
