| Abstract Scope |
Electrical properties are of significance for metals/alloys. While nanoparticles can enhance mechanical performance of metals/alloys, there is a strong need to understand how nanoparticles affect their electric behavior at various temperatures. In the study, ZrB2 nanoparticles were synthesized in situ to cast bulk Al-ZrB2 samples for electric characterizations. The electrical conductivity, electron mobility, and electron concentration of Al-3 vol% ZrB2 were measured in the temperature range from 2K to 300K. With a consideration to its compositions, morphologies, grain sizes, and nanophase sizes, the effects of in-situ ZrB2 nanoparticles on the Al matrix were systematically studied. It is discovered the Al-ZrB2 interfaces play a key role by tuning structural and electrical performances. This mechanism is important to better understand the electron behaviors in in-situ Al-matrix nanocomposites. The in-situ fabrication and electrical characterization methods can be readily applied to other metallic nanocomposites. |
