Abstract null null The influence of pulse current on microstructure and mechanical properties were investigated for friction stir welding (FSW) of 3 mm thick AZ31B Mg alloy with pulse current ranging from 0A to 400A. The grain size of SZ is the same of that of TMAZ as affected by pulse current, resulting in more smoothie transition of microstructure from the SZ to the HAZ. The ultimate tensile strength and elongation of EFSW joints both enhanced with increasing pulse current and fracture positio...

Abstract null null In this study, the effects of different ratios of graphene nanoparticle (GNP) and nanofibers on bonding connections were investigated. For that, with of adhesives DP410 and DP490 of AA5754 alloy samples were bonded with double patches using different ratios of graphene nanoparticle (GNP) and Nanofibers as interlayers. 0.1%, 0.2% and 0.3% ratios of graphene nanoparticle (GNP) were added to DP410 and DP490 adhesives. Samples that were the sizes of 75×30×3 mm of the AA5754 alloy ...

Abstract null null Due to the formation of excessive brittle compounds, the joint of Cf/C composites and single crystal Ni-based superalloy (DD3) has relatively low mechanical properties, greatly degrading the reliability of joints. In this work, an active Cu interlayer is introduced to adjust the interfacial reaction and microstructure of the joint. Effects of the Cu interlayer on the interfacial reaction and microstructure of joints are investigated in detail. Especially, the effect of the Cu ...

Abstract null null Selective laser melting (SLM) is an advanced, efficient and capable manufacturing technology that utilizes a laser for heating metal or alloy powders to melt and solidify directly into metal parts. In this paper, the smoothed particle hydrodynamics (SPH) method was employed for the three-dimensional numerical simulation of the SLM process. This method is significantly benefit for solving free surface flows and complex motions at multiple material phase interfaces. The weakly c...

Abstract null null The rapid pace of development seen in the metal additive manufacturing (AM) process of laser powder-bed fusion (LPBF) requires in-step advances in processes qualification to enable full-scale adoption. This particularly applies to quantifying how powder feedstock conditions impact end-component quality. This study examines how in-machine 17-4 stainless steel powder feedstocks are affected by prior LPBF processes, and how these effects impact subsequent builds. Examinations of ...

Abstract null null This work aims at enabling the fabrication of a new generation of prosthetic components with enhanced mechanical behaviour and an extended lifetime. Cobalt‑chromium lattice structures manufactured using laser powder bed fusion are analysed to quantify the influence of microstructural anisotropy and geometrical deviations on stiffness prediction. Results of the experimental campaign are used to improve finite-element modelling of the mechanical behaviour of functionally graded ...

Additive manufacturing has been adopted to process nickel-titanium shape memory alloys due to its advantages of flexibility and minimal defects. The current layer-by-layer method is accompanied by a complex temperature history, which is not beneficial to the final characteristics of shape memory alloys. In this study, a continuous directed energy deposition method has been proposed to improve microstructure uniformity. The spatial characterization of nickel-titanium shape memory alloy fabricated...
