Characterization and Heat Treatment of AA6061 with and without TiB2

Abstract

The properties of aluminium have been enhanced by addition of alloying elements like Cu,
TiB2, Si, Mg, Zn, Li, and Ni etc. The prepared castings are evaluated using optical
metallography, Image Analysis, and micro hardness testing. Morphological studies
confirmed that Al-5%Ti -1%B master alloy refines the grain size of the prepared castings.
For the hardness test the specimen is age hardened at 175°C for 8 hours. From the result the
heat treated samples have much more hardness and strength compared to the as cast
samples. In addition to that, AA6061 matrix alloy with and without TiB2 is also studied.
