Effects of the Processing Temperature of Centrifugal Casting on the Mechanical Properties of Al-Al3Ti FGMs
Formation of the compositional gradient in FGMs fabricated by centrifugal casting method depends mainly on the processing temperature and the applied centrifugal force. According to the initial state of the dispersed second phase at the processing temperature, CCM-FGMs can be classified into two categories. One is the FGM fabricated by centrifugal solid-particle method, and the other one is the FGM made by centrifugal in-situ method. In previous study, it has been reported that microstructure of Al-Al3Ti FGMs by centrifugal in-situ method was different from that by centrifugal solid-particle method. However, difference of mechanical property due to processing method is still unclear. In this study, mechanical properties, such as hardness and wear property of Al-Al3Ti FGMs fabricated by centrifugal solid-particle method and in-situ method were evaluated.
