Nano-sized reinforcements improved the mechanical characteristics efficiently by promoting more implicit particle hardening mechanisms compared to micron-sized reinforcements. particles lessen critical solidification velocity for swamp and thus offers better dispersal. In present investigation, friction stir processing (FSP) is utilized produce AZ31/Al2O3 nanocomposites at various tool rotation speeds (i.e., 900, 1200, 1500 rpm) with an optimized 1.5% volume alumina (Al2O3) reinforcement ratio. The corrosion behavior of AZ31/Al2O3-developed was investigated that AZ31 base alloy. alloy experienced a comprehensive dynamic recrystallization during FSP, causing substantial grain refinement. Grain-size strengthening primary factor contributed enhancement in strength fabricated nanocomposite. Tensile yield values were lower than those metal matrix, although upward trend both has been observed increase speed. An 19.72% hardness along superior resistance achieved rotational speed rpm. currents (Jcorr) all samples dropped speed, contrast potentials (Ecorr), which increased. Jcorr 42.3%, 56.8%, 65.5% chosen rotating rpm, respectively. processed have addressed this manuscript not given sufficient attention existing literature. Further, work effective choice quality assurance FSP process nanocomposites. obtained results are relevant development lightweight automobile aerospace structures components.

Strengthening aluminum matrix composite with additively manufactured 316L stainless steel lattice reinforcement: Processing methodology, mechanical performance and deformation mechanism

Journal of Materials Research and Technology, Год журнала: 2024, Номер 29, С. 1087 - 1101

Опубликована: Янв. 21, 2024

This study investigates various processing approaches, interface characteristics, and mechanical properties of an aluminum (Al) matrix composite reinforced with additively manufactured (AM) 316L stainless-steel (SS) lattice. The AM-316L-SS lattice, boasting a 30 % infill density, was fabricated using the laser powder bed fusion technique. Al-matrix integrated reinforcement through experimentation involving pre-stirring molten Al under pressurized unpressurized die-casting conditions. A well-bonded interface, cohesive regions, obtained in pre-stirred structures. In contrast, regions decohesion were displayed cast structures without pre-stirring, leading to presence pores manifestation imperfect bond interfaces. Compression tests conducted on sound demonstrated enhanced properties, compressive strength approximately 163 MPa, significantly higher than that pure (approximately 80 MPa). Localized cracking initiated by stress gradients plastic deformation, microcrack propagation into Al-matrix.
