ABSTRACT:
In this paper binary alloy of Al-Cu with composition Al(100-x)Cux,
(x = 10, 15, 20) is prepared by thermal evaporation method. The prepared
samples are annealed at different temperatures and investigated by XRD and
microhardness method. XRD has been used to show amorphous state of structures
and microhrdness tester show the increase in hardness due to the increase in
amount of Al in the alloy. SEM and AFM were also used to show information about
the surface of the specimen, resulting some densification and relaxation in
these specimens.
