Abstract

Microstructure and mechanical properties of Al-TiB2 nano surface composite fabricated by Friction Stir Processing (FSP)
were studied. Al6061-T6-TiB2 composite with 24% volumetric fraction of TiB2 was prepared using FSP. Microstructural
analysis confirmed the uniform distribution of TiB2 particles of 35nm size in the aluminium matrix after FSP.
Characterization of base metal, composite and TiB2 was done through OM, SEM, XRD and EDS. The phases present in base
metal, namely Al phase and Mg2Si phase are confirmed by optical microscope(OM), scanning electron microscope(SEM) and
X-ray diffraction (XRD). The newly formed phase of Al-Ti in the composite was also confirmed by XRD. Microhardness test
results show FSP of Al6061-T6 alloy with 24% TiB2 displays more hardness than base metal
