Processing and Microstructure of Magnesium In Situ Composite with Titanium and Boron Based Reinforcement

Article Preview

Abstract:

The present work is aimed to investigate the in-situ TiB/TiB2 particle formation in Mg and Mg-Al alloy via the chemical reaction between Mg, Al, K2TiF6 and KBF4. The feasibility to produce the Mg and Mg-Al matrix with in-situ TiB2 and TiB particles have been studied with respect to processing parameters. The XRD, optical microscopy and SEM-EDX analyses have been carried out on the synthesised composites. Significant improvement in the hardness values are obtained for the in-situ composite compared to the base alloys.
