RISEffect of welding parameters on the microstructure and mechanical properties of fraction stir welds of 70%Cu-30%Zn alloy (اثر یارامترهای جوشکاری روی ساختار میکروسکیی و خواص مکانیکی الیاژ Cu-Zn جوشکاری اصطکاکی شده)
سال: 2007
خلاصه:
Friction stir welding (FWS) is a relatively new method that uses a non-consumable rotating tool in order to create fractional heat and plastic deformation in the weld zone. It causes that the joint formation of h

Microstructural and mechanical properties of friction stir welded Cu–30Zn brass alloy at various feed speeds: Influence of stir bands
سال: 2011
خلاصه:
In this study, the effect of various feed speeds on microstructure and mechanical properties of friction stir welded Cu–30Zn brass alloy is investigated. Rotation speed was fixed at 950 rpm and feed speed varied in the ...
Establishing a correlation between interfacial microstructures and corrosion initiation sites in Al/Cu joints by SEM–EDS and AFM–SKPFM
سال: 2014
خلاصه:
A lap joint of AA3003 and pure copper was produced by friction stir welding and the induced interfaces
were investigated. Interfacial regions were characterized by SEM–EDS, AFM, SKPFM, OM and Vickers
micro-hardness. ...
