The mechanical properties, electrical conductivity, and thermal stability of a wire made of Al–Fe alloys produced by casting into an electromagnetic crystallizer

The development and production of new aluminum-based materials is a critical task the up-to-date industry. Particularly, are necessary to produce light, strong, thermally-stable wires cables for household usage, transport, power sphere. paper presents results study microstructure physical mechanical properties Al–0.5Fe Al–1.7Fe alloys (wt. %), produced by continuous casting into an electromagnetic crystallizer (EMC). authors carried out comparative analysis under commercial alloys. During this analysis, wire with diameter 3 mm from primary cast blanks cold drawing method (CD). showed that as result crystallizer, particles metastable modification Al2Fe phase appear during crystallization process have sizes close nanometric range. use led substructure formation in both refinement intermetallic particles, which ensured significant hardening alloy specimens. After drawing, were grinded distributed along boundaries grains/sub-grains. ultimate tensile strength was 204 MPa, while alloy, it reached 295 MPa. electrical conductivity level 58.4 52.0 % IACS, respectively. Al–Fe ferrum concentration up 1.7 wt. demonstrated thermal stability at Al–Zr Al–REM conductive
