“…RVEs with different sizes have been considered in previous studies (Ref 13 , 37 ). For example, Ma et al (Ref 37 ) found no significant difference in the tensile stress–strain responses by varying the RVE size from 20 µm to 50 µm.…”

This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al 2 O 3 ) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight fraction, particle size, and porosity) of the MMC coatings, 3D representative volume elements (RVEs) were generated by using Digimat software and then imported into ABAQUS/Explicit. State-of-the-art physics-based modeling approaches were incorporated into the model to account for particle cracking, interface debonding, and ductile failure of the matrix. This allowed for analysis and informing on the deformation and failure responses. The model was validated with experimental results for cold-sprayed Al-34 wt.% Al 2 O 3 and Al-46 wt.% Al 2 O 3 metal matrix composite coatings under quasi-static compression by comparing the stress versus strain histories and observed failure mechanisms (e.g., matrix ductile failure). The results showed that the computational framework is able to capture the response of this cold-sprayed material system under compression and indentation, both qualitatively and quantitatively. The outcomes of this work have implications for extending the model to materials design and for applications involving different types of loading in real-world application (e.g., erosion and fatigue).

“…RVEs with different sizes have been considered in previous studies [13,33]. For example, Ma et al [33] found no significant difference in the tensile stress-strain responses by varying the RVE size from 20 µm to 50 µm. In this study, an RVE length of 100 µm was considered based on the microstructural features (i.e., average particle size of 15 µm), which can be further explored in the future studies.…”

This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum-alumina (Al-Al2O3) metal matrix composite (MMCs) coatings subject to indentation and quasi-static compression. Based on microstructural features (i.e., particle weight fraction, particle size, and porosity) of the MMC coatings, representative volume elements (RVEs) were generated by using Digimat software and then imported into ABAQUS/Explicit. State-of-the-art physics-based modelling approaches were incorporated into the model to account for particle cracking, interface debonding, and ductile failure of the matrix. This allowed for analysis and informing on the deformation and failure responses. The model was validated with experimental results for cold-sprayed Al-18 wt.% Al2O3, Al-34 wt.% Al2O3, and Al-46 wt.% Al2O3 metal matrix composite coatings under quasi-static compression by comparing the stress versus strain histories and observed failure mechanisms (e.g., matrix ductile failure). The results showed that the computational framework is able to capture the response of this cold-sprayed material system under compression and indentation, both qualitatively and quantitatively.

“…In order to overcome these obstacles, the employment of intermetallic particles with better wettability and strong interfacial bonding with the matrix instead of conventional ceramic particles is one of the most prominent routes for reinforcement of Al alloys [6,7]. Intermetallics like Al3Ti, have lower brittleness and close coefficient of thermal expansion (CTE) to aluminum compared to the conventional ceramic components, and they also provide low density, high resistance to oxidation and corrosion, and high strength [8,9]. These properties make Al3Ti intermetallic a competent alternative for light structural applications [10].…”
