Abstract

Abstract: The aluminum matrix composites contained Al₂O₃ particles with different volume content were prepared by cold spraying additive manufacturing process,which included the volume fraction of 25%,50%,and 75%,respectively(i.e.Al-25Al₂O₃,Al-50Al₂O₃,and Al-75Al₂O₃).The influence of vacuum annealing treatment on microstructure and mechanical properties of cold sprayed aluminum matrix composites was analyzed by means of SEM,EBSD,hardness test and tensile test.The results show that the addition of Al₂O₃ particles increases the strength and hardness of the cold spray additive material,which enhances with the increase of Al₂O₃ content.The reason for this is that the hammer action of Al₂O₃ particles in the process of cold sprayed leads to mechanical interlocks and grain refinement due to severe plastic deformation and dynamic recrystallization.However,the strength and hardness of the material gradually decrease after annealing treatment,as well as thegradual increase of elongation.The internal structure of the material gradually become uniform.

Key words: Al-based composites, cold spray process, additive manufacturing, vacuum annealing treatment
