Abstract
In the frame of the common research project, manufacturing of thin sheet Ni-Ti based composites reinforced with Nb and TiB2 have been carried out through hot-forged bonding process for a high strength sandwich structure for the aeronautical engineering applications. Interface and bonding characteristics of hot forged composites have been evaluated heat treated at 550–600 °C depending on the operational parameters under laboratory conditions. Formability behaviour and delamination phenomenon have also been analysed by 3P Bending tests. An intermetallic phase layer has been carried out between the titanium and nickel sheet layers containing of hard particles reinforcements between the sheets by using hot forging process. Finally a high strength bonding has been carried out by mechanical joining and very strong chemical bonding diffusion during this process depending on the temperature and the time. With the finite element model developed with reference to these tests, the mechanical behaviour of the material is supported by simulations made with the Abaqus software. Finally, more detailed mechanical/physical properties of this developed material were investigated by applying wear and creep tests. Certain area in the microstructure have been analysed with SEM.
