Dual step stir casting method was utilized to develop Al6061 composite reinforced with SiC (micron) and Si3N4 (submicron) particles in varying proportion weight percentage. A homogeneous uniform distribution of hybrid reinforcement without significant porosity observed the microstructure composites. X-ray diffraction (XRD) results manifest that are thermodynamically stable during processing no ...

This article presents the investigative work conducted on the fracture toughness and microstructure of Al6061-9% graphite particulate composites. The requisite specimens for the fracture toughness testing were compact tension ones prepared using stir casting technique. The Al6061-9% graphite particulate metal matrix composite has been heat treated in the underaged condition. It is observed from...

This study enhances the strength of Al6061 alloy by adding Ti in form a rod using thermomechanical process, which would be useful making structures for aerospace and structural members. Two different properties material are joined together to new bimetallic material. Softer Al-6061 is used as sleeve, grade-II core. They were prepared with co-extrusion process at temperature 400 °C ratios 2:1 2:...

This study presents the crashworthiness performance of Al6061 tubes with stiffened quatrefoil sections under axial and oblique impact conditions. Influences different types stiffeners through depth in design a sectional crash absorber structure are investigated, numerically. Four stiffener patterns considered angles 0º, 10º, 20º, 30º measured from horizontal axis. Force-displacement characteris...

This research focuses on the study of simulation capabilities lagrangian (LAG) model and Smoothed Particle Hydrodynamics (SPH) for orthogonal dry machining aluminum alloy Al6061-T6. A three-dimensional finite element was developed verified using experimental data from published literature. The numerical models were boundary conditions via modeling in ABAQUS/Explicit 6.14. cutting simulations ca...

High-strength steel and aluminum alloys are used to manufacture modern vehicles. The objective was reduce the weight fuel consumption of In this study optimum parameters for friction stir spot welding (FSSW) process between Al6061-T6 alloy HSS590 high-strength were determined. Response surface methodology based on central composite design (CCD) with three parameters, five levels, 19 runs conduc...

Abstract Experimental and theoretical studies are combined to investigate the phenomenon of macroscopic plastic deformation localization in metallic tensile specimens AL6061, HSLA350 Q235. The longitudinal strain cross-section reduction at different instant during testing estimated through measurement technique three dimensional digital image correlation (3D-DIC). Ling weighted-average method r...
