Abstract

Al-Cualloy castings are obtained using centrifugal casting. The regularity of mechanical property gradient distribution ofAl-Cualloy castings with the same centrifugal radius at different positions is investigated. The result shows that the tensile strength, yield strength, elongation and microscope hardness exhibit the following gradient distribution characteristic — high on both sides and low on the center. The trend of mechanical property gradient distribution ofAl-Cualloy increases with the increase in the rotation speed. Moreover, the mechanical properties of casting centerline two sides have asymmetry. The reason is that the grain size of casting centerline two sides andAl2Cuphase andCucontent change correspondingly.
