摘要：
Atom probe tomography (APT) and high resolution transmission electron microscopy (HRTEM) were used to study the co-precipitation and coarsening mechanisms of Al-3(Zr1-x, V-x) precipitates formed in Al-Zr-V alloys. The strengthening mechanism that is operative in properly aged Al-Zr-V alloys are determined, and the antiphase boundary (APB) energy between the alpha-Al matrix and the Al3Zr precipitates and between the a-Al matrix and the Al-3(Zr1-x, V-x) precipitates is indirectly determined.
