摘要	The aim of the paper is to explore the deformation mechanism of particles in cold spray. Focused ion beam/scanning electronic microscopy (FIB/SEM) system was employed to prepare a TEM specimen of a whole copper particle on aluminum substrate on wipe test. Through analyzing the microstructure of the TEM sample, the result indicates that the inhomogeneous deformation of Cu particles is due to the inhomogeneity of stress field and temperature. During the impact, the kinetic energy of particles transforms to deformation energy and heat, which breaks the alumina layer and increases the temperature quickly. Because of high temperature and strain rate, re-crystallization happens in Cu near the interface and intermetallic compound Cu9Al4 is obtained on the interface. The farther the grains are from the interface, the less the influence on them. Heat or stress field have little effect on the grains far away from the interface, especially on the top of particle.
