Ageing Behaviour of Spray Cast Al-Zn-Mg-Cu Alloys
7xxx series aluminium alloys spray casting age hardening ageing precipitates TEM.
2009/10/13
Three 7xxx series aluminium SS70, N707 and 7075 alloys containing copper, zinc and magnesium were spray deposited using rapid solidification. Ageing of the 7075 alloy resulted in a peak hardnesses of ...
