The plastic deformation of the AlSi10Mg alloy manufactured via laser powder bed fusion (LPBF) is incompatible at microscale, which causes residual strains/stresses and dislocation pile-ups Al/Si interfaces grain boundaries. Hence, it fundamental significance to clarify these microscopic properties during deformation. Here, in-situ neutron diffraction employed explore strains, stresses, density in LPBF loading-unloading-reloading It found that maximum stresses Al Si phases loading direction...
The majority of aluminum alloys used for laser powder bed fusion are based on the aluminum–silicon system, particularly containing 7 to 12 wt.% silicon and less than 1 magnesium. Silicon has a beneficial influence melt viscosity during casting additive manufacturing prevents formation cracks. This study focused development new AlSi3.5Mg2.5 alloy with Mg-Si content above 1.85 Mg2Si, which is solubility limit α-aluminum matrix, subsequent heat treatment adjust mechanical properties wide range...
Abstract This paper investigates the mechanical properties of two selective lasermelted aluminum alloys (AlSi10Mg and AlSi3.5Mg2.5) under high strain-rate uniaxial loading. Accelerated tensile tests were performed various decades ( . ε = 4.7 × 10-3 up to 250 s-1) determine load-speed-specific changes in properties. As a result primary laser-based shaping process, microstructure characteristics change was entirely comparable conventional manufacturing parts. Based on an ultrafine...
The ductility of the Al alloys produced by additive manufacturing (AM) has become a critical property, as AM are increasingly used in automotive industry. However, as-built is relatively low, even with optimized conditions. post-annealing treatment provides an efficient way to improve ductility. Previous investigation shown that annealed AlSi3.5Mg2.5 alloy possesses superior plastic deformation micro-mechanisms remain unclear. In this study, in-situ neutron diffraction was employed explore...
