The effect of weld heat input on the formation of intermetallic compound (IMCs) layer during arc welding–brazing of aluminium and steel dissimilar alloys, was investigated through both finite element method (FEM) numerical simulations and experimental measurements. The results of FEM analysis as well as welding experiments indicated that increasing weld heat input increases the thickness of IMC...

Abstract: titanium sheets in pure molten aluminum at 750 and X-Ray Diffraction Analysis results, TiAlintermetallic layer thickness increases slowly at primary stages. After that an enhanced growth rate occurs due to layercracking and disruption. Presumably, reaction starts with solving titanium into the molten aluminum causing intitanium super saturation and TiAlintermetallic layer which conseq...

The use of Fe-Al intermetallic compound coatings has been investigated in order to improve the tribological behaviour of carbon tool steel. The coatings were formed by a pack cementation process and subsequently diffusion annealing at 900˚C in an argon controlled atmosphere. The optimum diffusion time was selected on the basis of optimum thickness and tribological behaviour. The microstructure...

The effects of magnesium alloy compositions on the interfacial microstructure, corrosion resistance and mechanical properties explosively welded alloys aluminum were investigated. bonding interface had a periodic wavy shape. Thin interlayer consists intermetallic compound, γ-Mg17Al12 phase, was formed at in all samples. When concentration is low, intermediate layer thin intermittently formed, b...

Effects of annealing treatment after equal channel angular pressing (ECAP) on the interface properties and shear bond strength of Al/Cu bimetallic rods were investigated. For the as-deformed samples, the one with two passes of ECAP indicated higher shear bond strength. Formation of a layer of intermetallic compounds after annealing treatment is confirmed. In general, by increasing annealing tem...
