The Boundary of X-Ray and Electron Tomography

January 3, 2005
Author(s)
Zachary H. Levine
Samples a few micrometers in total size offer a challenge to both x-ray and electron tomography. X-ray tomography originated imaging the human body with millimeter resolution, but the resolution has been reduced by over 7 orders of magnitude by the use of

2D and 3D Surface Texture Comparisons Using Autocorrelation Functions

January 1, 2005
Author(s)
Jun-Feng Song, Li Ma, Eric P. Whitenton, Theodore V. Vorburger
Autocorrelation and cross-correlation functions are proposed for 2D and 3D surface texture comparisons. At the maximum correlation point of the two correlated surface textures, there is a peak shown at the cross-correlation curve. It is proposed to

A Failure Analysis of an Experimental AIMgB14 Cutting Tools

January 1, 2005
Author(s)
J L. Evans, Laurent Deshayes, D G. Bhat, S A. Batzer
A recently developed ultra-hard boride-based material, AlMgB14, has been fabricated into a standard cutting tool geometry (TPG-222) and tested in the single-point turning of Ti-6Al-4V. The initial testing was conducted to compare this new cutting tool?s
