“…The composite coating is 33% harder and 12.5% stiffer than the Ni coating reference, which emphasises the metallic matrix reinforcement and which is in agreement with the literature. The composite coating is 33% harder and 12.5% stiffer than the Ni coating reference, which emphasises the metallic matrix reinforcement and which is in agreement with the literature [33-35]. However, according to the literature [36], such hardening effect may be the result of simultaneous phenomenon like an inherent flow behaviour (dislocations generation and interaction) and of the incorporation of hard dispersed particles (interaction between dislocations and particles/matrix interface).…”

Metal matrix composite coatings reinforced with hard ceramic particles are attracting growing interest due to their promising mechanical properties. In the present work, a thick nickel coating, containing micrometric Silicon Carbide (SiC) particles, was electro-deposited on a steel substrate from a suspension of SiC in a Watts-type Ni-plating bath. The texture and microstructure of the coating were examined using electron backscatter diffraction combined with energy-dispersive spectroscopy for phase differentiation. The interfacial strength between the Ni matrix and the SiC particles was investigated by nanoscratch experiments. Grid nanoindentation technique coupled with an image correlation-based targeted indentation analysis and a statistical data treatment were employed to quantify mechanical properties of the composite and to map and extract mechanical properties and fractions of each phase. Additional investigation of the mechanical properties of the coating was performed using peak force quantitative nanomechanical mapping experiments.

“…This is consistent with the change trend of the macro mechanical properties of the propellant [129]. Segurado and Llorca, Shoukry et al studied an RSA algorithm for generating the microstructure model of granular packing [130,131]. According to the application example of NPBA described in the US patent USP 4915755, Yu et al carried out mesoscopic simulation calculation of phase separation of three kinds of NPBA in various mixed energetic plasticizer/binder prepolymers by using molecular dynamics method.…”

Dewetting is the main damage mode of composite solid propellants, and the research on the initiation mechanism and evolution process of dewetting damage is an important way to predict the mechanical properties and evaluate the life of propellants. In this paper, the experimental research and analytical methods of dewettingare reviewed at domestic and foreign from three dimensions: macro, meso and micro. On this basis, the reference solutions to the existing research problems are proposed, and the key research directions of interface dewetting in the future are pointed out. The analysis shows that the dewetting behavior of composite solid propellant is affected by multiple factors such as internal factors (par-ticles, matrix, bonding agent) and external factors (temperature and humidity, aging, strain rate, confining pressure). At present, the mechanism of dewetting is not clear, so it is urgent to conduct experimental analysis and numerical simulation research on the interface at the micro level to analyze the physical and chemical properties of the interface. On the meso scale, it is necessary to increase research in the dewetting theoretical model considering multi factor coupling, the mechanical property experiment of particlematrix interface, and the fine construction of meso scale simulation model. On the macro scale, the dynamic analysis method of propellant dewetting under multiple complex loading conditions will be the focus of future research.

“…The off-axis tensile (OAT) test is considered as a viable method for characterizing the global, multiaxial stress-strain response of composites in the nonlinear deformation range [7][8][9][10][11]. Additionally, attempts are being made to formulate theoretical models that can be used in nonlinear stress analysis of continuous fiber and particulate MMCs under multiaxial stress states [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In the unit-cell and representative volume element (RVE) approaches [16][17][18][19][20][21][22][23], the composite is assumed to consist of a repeating array of units, each consisting of either a single fiber or an array of fibers embedded in a matrix material.…”

A Nonlinear Analysis Interpretation of Off-Axis Test Results in Metal Matrix Composites

A unit-cell based micromechanics approach is used to perform nonlinear finite element analyses of off-axis tensile tests on an SCS-6/Ti-6Al-4V composite. The results are used in predicting the global deformation response of the composite that includes the effect of fiber-matrix interface damage. The predictions are compared with laboratory test data of uniaxial off-axis specimens. Based on the comparison, it is found that the procedure effectively predicts global composite response with reasonable accuracy under a general multiaxial stress state.
