As a major one is TiC ceramic carbide (d ≤ 1–3 micron) at three levels (2.5%, 5%, 10%), whereas the minor addition of MoS2, Nb2Al and γ-Al2O3 fibre were fixed as 2, 3 and 3 wt %, respectively. These compositions are targets for the application of the connection link in a mechanism to transfer motion in aeronautical industry. For this reason, the machinability of these composites should be significant engineering case for the tailored behaviour of the composites produced through combined method of powder metallurgy route: sintering + Forging. Certain characteristics of the composites were carried out according to the optimization conditions of the reinforcements. Static and dynamic-crash tests will be performed. The microstructure analyses (matrix/interface) were carried out by Scanning Electron Microscope (SEM). A three-dimensional non-linear finite element model was used to simulate the static compression tests behaviour of these composites. A subroutine, VUMAT, will be written to use with ABAQUS/Explicit to analyze the effect of sintered-forging on the micro- and macrostructure of the manufactured materials. Different ratios of reinforcing particulates using in the experimental specimens were used in Representative Volume Element (RVE) (and other distribution techniques, etc.) for the microstructure modelling. Then, numerical models for the macrostructure were created using these micro-structures under the multiscale modelling process conditions.
