Abstract

The effect of stress peening on the surface layer characteristics of the TiB2/6351Al Composite including residual stress, microhardness and microstructures were investigated. The results show that the compressive residual stresses and microhardness were improved by stress peening. Microstructures investigation showed that, the deformation amount increased by stress peening which results in smaller domain size and higher density dislocations/microstrain. The more reinforcements distributed in the matrix played an important role in the compressive residual stresses increments and microstructures improvements. Stress peening is an effective method to improve the compressive residual stresses and the work-hardened state of the TiB2/6351Al Composite.
