Composition and structure of ultradispersed aluminum powders

X-radiographic, calorimetric, and atomic emission analysis were used to study the composition and structure of ultradispersed aluminum powders. The samples were obtained by electric arc plasma recondensation of aluminum, together with an alloying metal (copper, chromium, zinc, cobalt). It was established that the composition and structure of the alloyed ultradispersed aluminum powders depended on the nature of the alloying metal.
