Creation of composite bronze-maraging steel alloy

Abstract

The possibility is demonstrated of creating alloys based on the system Cu-Fe-Ni-Al, within which the matrix is bronze BrNA 4-1, "reinforced" with dendrites containing, apart from Fe and Cu, about 15% Ni and 1% Al. This dendrite composition provides dispersion hardening. Favorable dendrite morphology provides high deformability of these bronzes, and makes it possible to control mechanical and service properties by heat treatment over a wide range. © 2013 Springer Science+Business Media New York.
