Phase transformation behavior in Al-Zn-Cu alloys by hammering
The 5Cu40Zn55Al and 15Cu20Zn65Al alloys were prepared in the Al-Zn-Cu system.There exist the metastable phases ε and θ in the two alloys after homogenization treatment and furnace cooling,respectively.It is shown that the particles are refined from 3 mm to less than 10 μm after hammering the two alloys but there are still metastable phases.This means that the phase constituents of the two alloys have no changes by the deformation,which is different from that by balling.The phase constituents are not changed at room temperature by hammering,which is dependent on the deformation mechanism of hammering.
