Wear Resistance of Pre-ECAP Annealing A356 Al Alloy with 1.5 Wt.% TiB₂

Abstract:

The combination of heat treatment, addition of grain refiner and ECAP processing is used to improve mechanical properties and wear resistance of A356 Al alloys with 1.5 wt.% TiB₂. The alloys were grouped into as-cast and pre-ECAP annealing. The alloys were characterized with hardness and wear testing, optical microscopy and SEM. The ECAP processing was done through B_A route for 4 passes and it improved hardness, distribution of TiB₂ and Si particles in the aluminium matrix and increased wear resitance of pre-ECAP annealing specimen.
