Abstract
In this present investigation, a new approach for synthesizing intermetallic nitrides using metal jet has been developed. A metal jet induced from a conical shaped charge has been directed into liquid nitrogen. The source of the metal jet was aluminum, and it was penetrated into titanium powders submerged in liquid nitrogen. SEP, an explosive produced by Kayaku Japan Co. Ltd, was set on the aluminum cone, and this explosive was detonated by electric detonator placed on the top of the cone. In prior research, the metal jet velocity was estimated as 6km/s. This research investigated a range of separation distances between the cone and the target material. At the moderate condition, some bulk materials, which were composed of intermetallics like titanium nitride (TiN) and titanium aluminum nitrides (Ti_2AlN, Ti_3AlN), were recovered. The samples recovered were characterized for the microstructure using optical and scanned electron microscopes (SEM), and electron probe microanalyzers (EPMA).
