“…In the previous study, the transition interface layer was characterised in YAl 2 -reinforced Mg-14Li-3Al matrix composite, and the model considering interface layer was established for numerical study on the flow behaviour of the composite. [19,20] This paper aims to study the effects of particle/matrix interface and strengthening mechanisms on mechanical properties of the composites. With particular emphasis on their contribution, the significance of the contribution from these separate factors is evaluated.…”

2014) Effects of particle/matrix interface and strengthening mechanisms on the mechanical properties of metal matrix composites, Composite Interfaces, 21:5, 415-429, A randomly distributed multi-particle model considering the effects of particle/matrix interface and strengthening mechanisms introduced by the particles has been constructed. Particle shape, distribution, volume fraction and the particles/matrix interface due to the factors including element diffusion were considered in the model. The effects of strengthening mechanisms, caused by the introduction of particles on the mechanical properties of the composites, including grain refinement strengthening, dislocation strengthening and Orowan strengthening, are incorporated. In the model, the particles are assumed to have spheroidal shape, with uniform distribution of the centre, long axis length and inclination angle. The axis ratio follows a right half-normal distribution. Using Monte Carlo method, the location and shape parameters of the spheroids are randomly selected. The particle volume fraction is calculated using the area ratio of the spheroids. Then, the effects of particle/matrix interface and strengthening mechanism on the distribution of Mises stress and equivalent strain and the flow behaviour for the composites are discussed.
