Observations of Alloying in the Growth of Cr on Fe(001)

January 1, 1997
Author(s)
Angela Davies, Joseph A. Stroscio, Daniel T. Pierce, John Unguris, Robert Celotta
Using scanning tunneling microscopy, we observe the alloying of Cr with an Fe(001) substrate for various coverages at two temperatures. At low Cr coverage, the alloy consists of individual Cr impurities surrounded by Fe. Elemental identification is

On Chip Morphology, Tool Wear and Cutting Mechanics in Finish Hard Turning

January 1, 1997
Author(s)
Matthew A. Davies, Y K. Chou, Christopher J. Evans
Topography of surfaces produced in finish hard turning using cubic boron nitride (CBN) tools is affected by a large number of factors including tool wear and the mechanics of the chip formation process. This paper shows first that tool wear rates are

On the Dynamics of Chip Formation in Machining Hard Metals

January 1, 1997
Author(s)
Matthew A. Davies, Timothy J. Burns, Christopher J. Evans
The results of orthogonal cutting tests on electroplated Nickel-Phosphorus (15% phosphorus) and AISI 52100 bearing steel are presented and compared. For both materials, chips become segmented at relatively low cutting speeds (0.3 m/s to 2 m/s) due to the

On the Transition of KIF/Frame Ontologies to EXPRESS

January 1, 1997
Author(s)
Peter Wilson
This repot descibes the translation of three groups of ontologies specified using the Frame variant of the Knowledge Interchange Format (KIF) language into information models specified using the EXPRESS information modeling language, as defined in
