Abstract

"The U. S. Bureau of Mines at Rolla, Missouri has for some years been conducting research on manganese-copper alloys. The study of the physical metallurgy of these alloys -- dissimilar metal couples -- has always been complicated by the difficulty of satisfactorily etching this material. It was felt that by introducing a new etching technique, cathodic bombardment, satisfactory etching might be accomplished. On this basis the following research program was proposed:

1) To survey the present state of art of cathodic etching, etching by means of cathodic sputtering;

2) To design and construct suitable equipment for the experimental study of etching of manganese copper alloys by means of cathodic sputtering;

3) To investigate the cathodic etching of cast and wrought manganese copper alloys, considering the effects produced by variations in atmosphere, voltage current, and geometry of the etching chamber, and in composition, grain size, orientation, electrical properties, and heat treatment of the alloy specimens;

4) To master the necessary techniques of polishing, etching, replicating and shadowing to present ultimate results of the above investigation in the form of electron and light micrographs of good quality"--Introduction, pages 2-3.
