Engineering of strong and hard in-situ Al-Al3Ti nanocomposite via high-energy ball milling and spark plasma sintering

Light-weight Al-Ti nanocomposites attract increasing attention due to the advancements in spacecraft and additive manufacturing. In this work, ab initio modeling, DSC, and in-situ XRD experiments were used to formulate a strategy for rapid fabrication of Al-Al3Ti nanocomposites with enhanced mechanical properties (ultimate tensile strength up to 437 MPa at room temperature and up to 109 MPa at 500 °С, ~6% elongation before failure), resulting...
