Abstract: The fracture behavior of a spray deposited AlSiFe alloy during tensile deformation has been studied. The results showed that the microcracks initiated both inside Si phases and at the boundaries of Si phases with the matrix during the tension. Some microcracks inside Si phases existed before tensile deformation, while the others generated due to the brittle fracture of Si phase during tension deformation. Microcracks at the boundaries of Si phase with matrix were caused by microporosity and bad mechanical connecting between them. The failure of the materials occurred through joining of these microcracks.
