Abstract Friction stir processing (FSP) was used to modify the surface layer of AZ91 magnesium alloy. The treatment carried out using a jet cooling nozzle, generating stream cold air and enabling intensive friction processed (FSPed) zone. Single-pass FSP tool rotational speed 500 rpm travel 30 mm/min. conducted truncated cone-shaped with threaded side surface. Strong grain refinement microstruc...

Generally properties of as-cast AZ91 soft Mg-alloy can be improved by conventional artificial aging. Conventional methods are time consuming and expensive process. Friction stir processing (FSP) based on working principle welding replace the processes at some extent. FSP generates enough heat in process to decrease grain size coarse grains significantly accordingly alter properties. extensive u...

In this work, the feasibility test of friction stir processing (FSP) 1.5-mm-thick austenitic stainless steel cold spray coating deposited on 304L substrate was performed using tungsten carbide tool. Applied FSP parameters (advance speed 50 mm/min, rotation 300 rpm, axial force 20 kN, tilt angle 1.5°) allowed to perform treatment with a higher depth than thickness. As result, material mixing at ...

Friction Stir Processing (FSP) is a solid-state method that widely used in titanium and its alloys to enhance their strength. The FSP technique produces low-defect-density materials with improved mechanical properties, making it potentially valuable for orthopedic dental applications. It primarily low-melting-point such as but can also be applied high-melting-point metals steel, nickel, alloys....

Magnesium alloy composites play an important role in the biomaterials field. In this study, a novel Mg-Zn-Ca matrix composite was reinforced by adding 1.0 wt.% MgO nanoparticles via high shear casting process. Hereafter, friction stir processing (FSP) used to achieve good dispersion of particles and improve mechanical properties composites. After preparation materials, varied characterization p...

Structural Health Monitoring systems assess the part's current condition. This can be performed with a monitoring system comprising sensors, on surface or embedded, in monitored parts. However, sensors are subject to damage, and embedding may result weakened part. An innovative Self-Sensing Material its manufacturing process were developed presented herein. As proof of concept, Barium Titanate ...

in this research, surface composite layers containing nano sized tib2, al2o3-tib2, zro2 and cnt particles have been fabricated on aluminum alloy substrates by friction stir processing. the effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nanocomposite layers have been evaluated by electron micros...
