Intermetallic Composites.
PhD thesis, Universiti Sains Malaysia.
Abstract
The purpose of this study is to synthesize iron aluminide intermetallic composite
with in situ particulates (Al2O3, TiB2, TiC). Powder metallurgy method was used in this
work to produce iron aluminide solid solution as matrix by mechanical alloying. It was
found that mechanical alloying process plays a significant role in solid solution
formation and later on the mechanical properties. The optimum conditions to produce
iron aluminide composite in this particular work are: (1) milling time is 10 h at speed of
300 rpm, (2) consolidation by hydraulic press at 350 MPa and (3) sintering at 1300 oC
for 1 h. Matrix of iron aluminide can form Fe3Al or FeAl depending on the Al
concentration.
