To improve the properties of AZ31B Mg alloy and for first time, rare earth cerium oxide (CeO2) zirconium dioxide (ZrO2) were combined synergistic benefits introduced into structural magnesium through solid-state friction stir processing procedure to form hybridized Mg/ZrO2+CeO2 composites under variable levels tool's rotational speed up 1200 rpm. The macro-/microstructure, hardness, shear punching strength, tensile corrosion behaviours, tribological characteristics such as weight/wear loss,...
Modified friction stir clinching (MFSC) process was employed to joint dissimilar AA2024-T3 and AA6061-T6 Al sheets by interchanging the upper lower during joining process. The material flow, microstructure, tensile strength fracture behaviors of MFSC joints were studied. results reveal that positioning significantly affects flow behavior due disparity in properties (flow stress) alloys. flow-induced hook path proximity tip geometric differential defect (at refilled end keyhole) are...
The integration of flow-induced mechanical interlocking, interlayer-controlled atomic diffusion and self-reacting brazing benefit is employed to achieve an improved load-bearing performance the dissimilar AA2024-T3/copper joint via use Dieless Friction Stir Extrusion-Brazing (DFSE-B). A comparative study (DFSE-B) Spot Welding-Brazing (FSSW-B) AA2024-T3/Cu was investigated by using a 100 µm thick Zn interlayer. microstructure, tensile-shear load, fracture modes respective joints were...
The mixture of the rare-earth CeO2 and ZrO2 particulates was used for fabricating hybridized AZ31BMg/(CeO2+ZrO2)p composites by utilizing friction stir processing with a multiple-tool pass strategy. structure, mechanical properties (tensile strength hardness), tribological performances (wear properties) corrosion behaviours hybrid were examined. findings reveal elimination tunnel-like defects clustering CeO2+ZrO2 particles in composite after multiple passes tool due to successive...
In this work, the AZ31 Mg alloy was subjected to friction stir processing (FSP) by adding CuO and ZrO2 particles. The main aim of study increase tribological mechanical behavior AZ 31/(CuO + ZrO2)p surface composite in air water. influence media on microstructural modification properties developed composites is assessed via optical microscopy (OM), scanning electron (SEM), transmission (TEM), shear punch testing (SPT) Vickers hardness testing. It had been found that finer grains are produced...
Refractory high-entropy alloys (RHEAs) contain alloying elements with a high melting point, promising high-temperature applications due to their unique properties. In this work, laser cladding is used prepare RHEAS based on NbMoTaTiNi. At the same time as cladding, ultrasonic field used, and then microstructural characteristics, grain size, residual stress, wear, hardness of coating are evaluated. The results show that biphasic includes γ (Ni) NbMoTaTiNi phase. phase had uniform distribution...
