Journal ArticleDOI
Preparation and corrosion resistance of pulse electrodeposited Zn and Zn–SiC nanocomposite coatings
TL;DR: In this paper, a pure Zn and Zn matrix composite coatings containing nano-sized SiC particles with an average size of 50nm were prepared from the zinc sulfate bath.
Journal ArticleDOI
The effect of FSP on mechanical, tribological, and corrosion behavior of composite layer developed on magnesium AZ91 alloy surface
TL;DR: In this article, surface composites were developed on the surface of AZ91 magnesium base alloy and SiC and Al2O3 particles were embedded separately in the surface and accordingly two kinds of composites are developed.
Journal ArticleDOI
The effect of changing chemical composition on dissimilar Mg/Al friction stir welded butt joints using zinc interlayer
Amin Abdollahzadeh,Amin Abdollahzadeh,Ali Shokuhfar,José-María Cabrera,A.P. Zhilyaev,A.P. Zhilyaev,Hamid Omidvar +6 more
TL;DR: In this paper, solid state joining technology of friction stir welding (FSW) was carried out for Al and Mg butt joints, and the fracture micrographs were compatible with the corresponding ductility results and fracture surfaces of Zn added samples possessed a fine texture combining brittle and ductile fracture features.
Journal ArticleDOI
Influence of bonding variables on transient liquid phase bonding behavior of nickel based superalloy IN-738LC
TL;DR: In this article, the effect of process variables on the microstructure and properties of transient liquid phase (TLP) bonded IN-738LC superalloy was investigated using AMS 4776 filler metal.
Journal ArticleDOI
In-situ nanocomposite in friction stir welding of 6061-T6 aluminum alloy to AZ31 magnesium alloy
Amin Abdollahzadeh,Amin Abdollahzadeh,Ali Shokuhfar,José-María Cabrera,Alexander P. Zhilyaev,Alexander P. Zhilyaev,Hamid Omidvar +6 more
TL;DR: In this article, a combination of two travel speeds (25 and 35mm/min) and three rotation speeds (550, 600 and 650mm/rpm) were employed to obtain the optimal conditions for FSW of AZ31 magnesium alloy to 6061 aluminum alloy.
