Comparative study on properties of in situ particles reinforced Al-Si-X (Mg, Ti, Ni) composites by centrifugal casting
In this study, Al-Si-X (Mg, Ti, Ni) composite tubular castings were prepared by centrifugal casting. The segregation behavior of primary particles formed in different alloys under the action of centrifugal field was analyzed, and the hardness and wear resistance of different composites were tested. The results show that primary Si/Mg2Si particle reinforcement layer is formed in the inner layer of the casting by Al-Si-Mg composite, the primary TiAlSi particle reinforcement layer is formed in the outer layer of the casting by Al-Si-Ti composites, and the primary NiAb3/Si particle reinforcement layer is formed in the inner and outer layers of the casting for Al-Si-Ni composites, respectively. The hardness of particle reinforced layer in Al-18Si-7Mg (Ti, Ni) alloy castings reaches HRB71.5, HRB67 and HRB67.5, respectively. The volume wear of Al-18Si-7Mg alloy is the least. The difference of hardness and wear resistance of particle reinforcement layer is mainly related to the volume fraction, size and particle morphology of primary particles in the alloy.
