| 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. |
