© 2022, The Society for Experimental Mechanics.In the frame of the common research project, manufacturing of scrap thin sheet “Ni-Ti-Al” based composites reinforced with Nb2Al/TiB2 have been carried out through hot-forged bonding process of the composites for a high strength sandwich structure (>1500 MPa). Interface and bonding characteristics have also been examined of hot-forged composites, heat treated at 550 °C depending on the operational parameters under laboratory conditions. Formability behaviour and delamination phenomenon have been analysed by 3P bending tests. An intermetallic phase layer has been carried out between the titanium and aluminium sheets containing hard particles reinforcements during hot forging process. Finally, a high strength bonding has been carried out by mechanical joining and mutual chemical bonding diffusion during this process as a function of process temperature and time. Numerical Approach: At this stage of the project, the primary objective would be to establish a continuum-based material model in order to capture the macroscopic behaviour of the targeted composite materials and numerically reproduce the results from the basic characterization tests (bending). The model was implemented for Finite Element Analysis Software ABAQUS/Explicit as a user subroutine VUMAT for explicit nonlinear finite element calculations. The second step would be modelling of the microstructure of the proposed hybrid Ni-Ti-Al based composites and simulate the behaviour of several RVEs and see the effect of the sintered-forging and different ratios of reinforcing particulates.
