Abstract Scope |
Aluminum’s large freezing range and high reflectivity greatly reduce its compatibility with AM. This hinders development of laser-based aluminum AM and deteriorates the existing lack of lightweight structural materials in the intermediate temperature range. Aluminum matrix composites (AMCs) have great potential as thermally stable lightweight structural materials. However, it's fabrication largely uses conventional methods, achieving only moderate volume fraction of reinforcement while having limited part complexity. In-situ reactive printing (IRP) is adopted as a novel method, harnessing the reaction product of dissimilar elemental powder mix to fabricate AMC with an ultra-high volume fraction of intermetallic reinforcement. In this study, the effect of titanium addition to elemental aluminum feedstock powder is systematically studied on different aspects including material processability, microstructural features and mechanical performances. The results show that IRP can overcome the incompatibility between AM and aluminum and produce AMC with exceptional volume fraction of reinforcements when compared to existing counterparts. |
