Diamond Compounds for Polishing Metallographic Specimens,en though a significant quantity of the micron-size diamonds that are produced each year are consumed in the preparation of metallographic samples, only very limited technical information has been made available to the metallographer to enable him to determine what characteristics a diamond compound

Linde Alumina Abrasives for Metallographic Polishing,e them suitable for a given lapping or polishing process need. The purpose of this paper is to describe in some detail the special manner by which LINDE* Alumina Abrasives are prepared by chemical means without need for subsequent classification. This makes them especially suitable for metallographi

Mounting, Lapping and Polishing Large Sizes and Quantities of Metallographic Specimens,rk. In the beginning, most samples were small, were cut to size with a hacksaw, filed, sanded on abrasive paper and then polished using various materials on a variety of cloths. Although, through the years, methods, materials and equipment gradually improved, there were limitations, particularly in

Techniques of Specimen Preparation for Metallography Using a New and Unique Automated Polishing Proof a wide range of materials. These included soft materials (lead alloys), brittle materials (coal, oxide coatings), sensitive materials (austenitic stainless steel, zinc alloys) and hard materials (carbides, iron ore pellets). It was also found that the polishing characteristics of the system were

Mechanical Preparation of Gd3Ga5012 and Various Electronic Materials by Vibratory Polishing Techniqes that are flat, free of scratches and pits, and with minimal residual surface strain. These requirements must be achieved both for chemical vapor deposition (CVD) and liquid phase epitaxial (LPE) deposition of rare-earth magnetic oxides. The procedure described in this paper is basic to the prepar

Metallographic Methods Applied to Ultrathinning Lunar Rocks, Meteorites, Fossils, and Other Brittles H. C. Sorby, actually started metallography on its way. Since Sorby’s day, metallography and the preparation of metallic specimens have come a long way. During the same period, optical petrography has remained very static and conservative.

Plutonium Metallography,e been shared by plutonium and uranium (1,2). The groundwork for their elevation to such prominent positions was laid in 1919 by Rutherford’s work on nuclear disintegration. The twenty years following his revelation that atomic nucleii are not indestructible saw first a relatively slow advance in ph
