“…One of the key advantages of FSP is its ability to join dissimilar materials and produce complex shapes with high precision [24]. This makes it particularly well-suited for fabricating aluminum composites, where uniform mixing and distribution of reinforcing agents are crucial for optimizing material properties [25][26][27][28]. Additionally, FSP offers several benefits over conventional welding techniques, including lower distortion, reduced residual stresses, and improved mechanical properties.…”

In the realm of composite manufacturing, this study delves into the innovative approach of enhancing Aluminum-Based Composite Manufacturing through Si3N4 Reinforcement leveraged via Friction Stir Process (FSP). The FSP technique, executed with precision using a vertical milling machine, intricately fabricates composite materials with unparalleled properties. Meticulously chosen parameters including pin diameter, tool tilt angle, and tool profile, coupled with precise tool traversal and rotation, define the operation. The composite substrate, composed of AA 2024, undergoes stringent cleanliness protocols before Si3N4 powders are strategically placed into a designated groove on the titanium surface for processing. Microscopic examination reveals the uniform dispersion of Si3N4 particles within the aluminum matrix, profoundly enhancing mechanical properties. The tensile strength experiences a remarkable 21.45% improvement, while hardness witnesses a significant enhancement of 36.9%. Additionally, fatigue strength is notably improved by 24.12%, and wear resistance sees a substantial boost of 30.44% following Si3N4 nanoparticle integration via FSP.

“…Various amounts of sugarcane bagasse ash were incorporated into the Al6061/5 wt.-% aluminium oxide composite following the stir casting route and found to increase tensile strength and hardness [11]. Many researchers have worked on hybrid composites having aluminium and aluminium alloys as matrix along with sugarcane bagasse ash and other constituents as reinforcements [10,[12][13][14][15]. The results revealed the enhanced mechanical properties of aluminium metal matrix composites.…”

Burnt sugarcane bagasse powder (SCBP), with its low density, accessibility, and renewal, is an economically reinforcing material. This study fabricated composites, i. e., aluminium/alumina/burnt sugarcane bagasse powder, through the powder metallurgy route. The physical, mechanical, microscopic, and chemical characterization of the composites, such as relative density, microhardness, uniaxial compression, scanning electron microscopy, and x‐ray diffraction, has been conducted. There is a gain in relative density, microhardness and ultimate compression strength of about 2.25 %, 48.07 % and 33.34 % respectively, compared to the base composite (aluminium/4 wt.‐% alumina) at 3 wt.‐% burnt sugarcane bagasse powder. The Taguchi methodology is used as a statistical tool to optimise the response variables. An analysis of variance (ANOVA) is used to find the contribution of input parameters to response variables, and the regression models have been developed. The contribution of factors ‘burnt sugarcane bagasse powder wt.‐%’ and ‘time’ on relative density is 81.65 % and 13.64 %, respectively, while the contribution of the same factors on microhardness is 95.98 % and 3.377 %, respectively. The results of the Taguchi method reveal that the optimised conditions for the highest relative density and microhardness are 3 wt.‐% burnt sugarcane bagasse powder and 2.5 h, which have confirmed the experimental results.

“…The tensile strength of SiO 2 was approximately 10 times lower than that of SiNx, whose strength ranged between 57-69 30) and 525 MPa. 31) Therefore, the presence of residual oxide film can be a factor that contributed to the reduced burst pressure of the SiNx membrane. To verify the effect of this residual oxide film on the membrane's burst pressure, one must keep the total thickness of the SiNx and SiO 2 layers constant and change the SiO 2 layer thickness.…”

We would like to improve detection sensitivity by making photoelectron transmission window (SiNx membrane) of liquid cell ultra-thin for liquid measurement using XPS or X-ray PEEM at UHV. In this study, thinning of the membrane using gas cluster ion beams (GCIB) was demonstrated and the burst pressure was compared with those thinned with atomic 400 eV Ar+ ions. It was shown that SiNx membranes thinned by GCIB was 2.5 times higher burst pressure than the Ar+ ions. In addition, improvement of sensitivity of characteristic X-ray from liquid-water induced by low-energy electrons was investigated. By using 4.5 nm thick SiNx membrane etched by GCIB, the X-ray intensity became 1.6 times higher than those from 11 nm thick pristine membrane at electron beam energy of 1.5 keV. This result showed good agreement with Monte Carlo simulation results of the electron-beam-induced X-ray emission from liquid-water beneath SiNx membrane.
