ABSTRACT
By the method of penetrating gamma radiation in the temperature range of 300–1500 K, the density of aluminum and alloys based on it, containing 3 and 5 wt % V. It is shown that an abrupt decrease in the density of the samples associated with the transition to the liquid state is observed with increasing temperature. After melting, a non-monotonic change in density is observed, associated with the presence of intermetallic compounds with different melting points in the studied region of the Al-V phase diagram. The structural features of the melts are used to optimize the production of Al-V powders for 3D printing by selective laser fusion.
KEY WORDS:
aluminum alloys and powders, density in the Al-V system, alloy structure and morphology, particle size distribution, 3D printing.
