Synthesis and characterization of a new high entropy composite matrix

Year: 2016

Type: conference-paper

Abstract: Even if high entropy alloys were not reported in a scientific journal till 2003, these new alloys have been investigated since 1995 due to their high temperature properties.In the last years the synthesis of these alloys has been widely investigated.Thus, the present work has been carried out to produce a high entropy composite using an equiatomic AlCrFeMnNi high entropy alloy (HEA) matrix and graphite particles (Gr) as reinforcing material.The high entropy composite was obtained by powder metallurgy route using a planetary ball mill.The mechanically alloyed mixture was investigated by scanning electron microscopy (SEM).Microstructural investigation realized by SEM revealed the homogenous structure of the composite, with multiple phases and decreasing particles size, mostly reaching nanometric scale.
