Achieving simultaneously improved tensile strength and ductility of a nano-TiB2/AlSi10Mg composite produced by cold spray additive manufacturing

Abstract: The premature failure of components due to poor inter-particle bonding is the most critical issue in cold spray (CS) additive manufacturing. Herein, a hybrid strategy combining gas-atomization (involving in-situ reaction), CS, and post-friction stir processing was proposed to design a nano-TiB2/AlSi10Mg composite. Multiscale characterization in terms of X-ray diffraction and scanning and transmission electron microscopy was conducted to track microstructure evolution for understanding the mechanisms determinin… Show more

“…including heat treatment, hot rolling (HR), and FSP, as well as the Al alloy parts produced by SLM and casting [73,76,125,126,138,[149][150][151][152][153][154][155]. Heat treatments are commonly used to relieve residual stress and to further improve the mechanical properties of the as-sprayed deposits or components.…”

“…ImageJ image analysis software (NIH, USA), was used to quantify the porosity, thickness, mean free path and alumina content in the coatings using the greyscale thresholding technique. Five SEM SE images of area 1000 × 1000 µm 2 were used for measuring the thickness of the coatings, while five lower magnification BSE SEM images of area 300 × 300 µm 2 were used for measuring the porosity, the volume fraction of alumina retained in the coatings and the mean free path of the coatings. The volume fraction of the alumina in the coating was converted to wt% by using Eq.…”

“…MMC coatings combine the properties of a ductile metallic matrix and the high strength of a reinforcement phase for a specific performance [1]. Commonly used reinforcement particles in MMC coatings include ceramic particles (Al 2 O 3 , SiC, B 4 C, TiB 2 ) [2], carbon fibre, synthetic diamond particles [3], carbon nanotubes and graphene [4]. The size, weight fraction and distribution of the reinforcement particles and the interfacial bonding between the matrix and reinforcement predominately determine the properties of MMC coatings [5].…”

“…Inadequate wear resistance and deprived performance at elevated temperatures are major concerns of aluminum alloys [1]. These deficiencies are generally overcome by introducing reinforced particles in such alloys to produce aluminum matrix composites (AMCs) [2][3][4][5]. Reinforced particles in the metal matrix improve the mechanical characteristics of AMCs by modifying the microstructural attributes.…”
