Nickel-Aluminium intermetallic-based composites are potential applications in aeronautical industry as a multifunctional materials. In this work, recycled Ni–Al-based composites reinforced with TiB2 and TiC were fabricated by using powder metallurgy-combined method sinter + forging. Stress relaxation tests are aimed to explain deformation mechanism with the specimens treated under the extreme conditions (Humidity, temperature, etc.). As a result, mechanical properties of the sintered forging composites were considerably improved. Mechanical and Physical–Chemical properties were measured. Diffusion mechanism at the matric-reinforcement interface are also investigated by using Scanning Electron Microscopy (SEM).

摘要

Nickel-Aluminium intermetallic-based composites are potential applications in aeronautical industry as a multifunctional materials.

Stress relaxation tests are aimed to explain deformation mechanism with the specimens treated under the extreme conditions (Humidity, temperature, etc.). As a result, mechanical properties of the sintered forging composites were considerably improved. Mechanical and Physical–Chemical properties were measured. Diffusion mechanism at the matric-reinforcement interface are also investigated by using Scanning Electron Microscopy (SEM).
