| Abstract Scope |
The present investigation aims to develop stable nanocrystalline(NC) Aluminum(Al) alloys by doping them with Silicon(Si) and Lanthanum(La). To prepare NC powders, cryomilling was performed on a blended mixture of Al-Si, and Al-La powders for varying durations. The powders were then analyzed using scanning electron microscopy(SEM) and energy dispersive spectroscopy (EDS) to explore the effect of the cryomilling on the morphology and the elemental distribution of the dopants in the Al matrix. Apart from this, X-ray diffraction(XRD) analysis was also conducted showing that the crystallite size decreases with an increase in cryomilling duration, and the addition of dopants leads to a greater reduction in crystallite size. Moreover, the doped NC powders also showed improved thermal stability at elevated temperatures. This study provides insight into the development of bulk stable nanomaterials with superior mechanical properties for lightweight applications, for instance in the automotive, aerospace, marine, and nuclear sectors. |
