The high entropy alloy (HEA) filler used during the fabrication method determines reliability of HEAs for steel-aluminum dissimilar configuration. have a direct impact on formation intermetallic compounds (IMC) formed by interaction iron (Fe) and aluminum (Al), influence size joint’s zone. A novel welding process Fe-Al joints was developed to prevent development brittle iron-aluminum interface....

This paper presents deformation and cracking phenomena associated with the cold spray of nanoscale surface oxide layers 6061 Al alloy powders. The structure top film was revealed via Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS). observations show layer characteristics most likely matches crystalline γ-Al 2 O 3 . Phenomena contacts, conta...

Particle effects on friction and wear of 6061 aluminium (6061 AI) reinforced with silicon carbide (SIC) and alumina (AI203) particles were investigated by means of Vickers microhardness measurements and scratch tests. Unreinforced 6061 AI matrix alloy was also studied for comparison. To explore the effect of heat treatment, materials subjected to three different heat treatment conditions, i.e. ...

A nanocarbon-infused aluminum-matrix composite, termed "covetic," has been developed by Third Millennium Metals, LLC, and we have evaluated the enhanced performance prospects for strength and electrical conductivity. This paper examines the effects of the nanoscale carbon on the physical, electrical and mechanical properties of the metal-matrix composite based on microscopy, hardness, quasi-sta...

Although very accurate in representing the material anisotropy, finite element analysis based on direct use of a polycrystal model is CPU-intensive (Guan et al., 2006a). In the present study, this Taylor-type polycrystalline model was firstly used to predict the anisotropy coefficients of Yld96 yield function. Then this phenomenological anisotropic yield function was implemented into ABAQUS/Sta...

Continuous production of Al 6061-T6 particulate using modulation-assisted machining (MAM) is demonstrated. Superimposition of a controlled, low-frequency modulation in conventional machining causes chips to form as discrete particles. By adjusting the conditions, equiaxed, platelet and fiber-shaped particles having narrow size distributions can be produced. Large-strain deformation leads to mic...
