Abstract The present endeavour is to augment mechanical attributes via friction stir processing (FSP) in hypereutectic aluminium–silicon castings by the means of microstructural modifications and defects reduction. Wherein, study proceeds with mainly two approaches namely, alteration tool revolution (TR) number FSP passes. prepared specimens were evaluated investigating volume fraction porositi...

Fifteen patients with CT-documented orbital lesions were evaluated with MR imaging at 1.5 T with both conventional spin-echo (SE) and short inversion time inversion recovery (STIR) sequences. Fat signal was reliably nulled at inversion times of approximately 120-200 msec in all cases, thereby allowing clear detection of all retrobulbar lesions and normal structures on STIR images as markedly hy...

A recent paper on MR imaging of infectious spondylitis [1) elaborated on and substantiated a previous report [2) of STIR in the evaluation of spinal infection. However, it also contained an important error in pulse sequence nomenclature: STIR was described as "short T1 inversion recovery. " The STIR sequence was described and named by Drs. Bydder, Young, and Steiner [3 , 4) as "short Tl inversi...

The potentiodynamic polarization of aluminium 6063 alloy reinforced with silicon carbide (SiC) and palm kernel shell ash (PKSA) particulates at various mixing ratios were investigated. Double stir casting method was adopted for the production hybrid composites. existence reinforcements within matrix acted as active sites corrosion initiation. Hence, pitting observed. range values Ecorr Icorr ob...

This study investigates the mechanical properties and wear behavior of Al 7075/Al2O3/SiCNP composites. The hybrid composites are manufactured using stir casting technique. In this work, 7075 alloy is reinforced with five different weight fractions Al2O3 a constant SiCNp, an average particle size 50 nm. aluminum metal matrix examined through surface morphology X-ray diffraction (XRD) patterns to...

Hybrid aluminum composites obtained with stir casting were investigated in this study. Aluminum alloy EN AW 6061 was reinforced particles of Al2O3 and walnut-shell ash (WSA). The weight fraction constant (5 w/%) for the ash, it (1, 2 3) w/%. morphology particle distribution examined an optical microscope scanning electron microscope. Microstructural studies showed a uniform all samples. A chemi...

The impact of wear factors on composite materials is examined in this article. Stir casting was used to produce AA7075 alloys with varied nano-zirconium boride weight ratios. dry sliding test done utilizing pin-on-disc equipment. L27 orthogonal array built by Taguchi’s experiments for optimization. We calculated the proportion responses that could be attributed input parameters using SNR and AN...

Aluminum matrix composites (AMCs), reinforced with SiC and Mo, are formulated using stir casting. The influence of Mo inclusions on microstructural behavior, machinability was investigated. Microstructural behavior is analyzed scanning electron microscopy (SEM), X-ray diffraction (XRD) energy dispersive spectroscopy (EDS) in the form microhardness, tensile strength, wear density, porosity as pe...
