Ballistic Compressor Examination of Electrodeposited Niobium.

Abstract

As part of a program to simultaneously examine the capabilities of the MTL ballistic compressor and to characterize materials, a series of high pressure, high temperature shots were made on specimens of niobium electrodeposited on a copper substrate. Each shot allowed the test gas to flow through an experimental channel. The resulting surfaces were examined optically and by scanning electron microscopy, and mass loss was measured. On the basis of these, it was noted that the niobium offered a measure of protection to the underlying material, and underwent a different damage mechanism than does steel. This mechanism is elucidated.
