The damping capacities (Q-1) of high silicon (6wt%) Zinc-27wt% Aluminia alloy prepared by spray deposition and conventional casting process were investigated. Three methods, free-decay, half-power band width and phase angles difference, have been ased to measure the damping capacities of the experimental materiale. The experimental results indicate that the damping capacity of spray deposited material is 3.7times larger than that of the conventional casting alloy ZA27 The machanism for its improvement was aiso investigated from a microstructvre viempoint. 展开更多

The elevated temperature creep properties(90-150℃) of high silicon(~6wt%Si) alloy ZA27 prepared by spray deposition have been investigated by means of ball hardness testing method.The results indicate that the creep properties of the material prepared by spray deposition are notably improved,compared to that of the conventional casting alloy ZA27.The creep activation energy of the spray deposited alloy ZA27 is 3.9-5.7 kJ/mol higher than that of the conventional casting alloy ZA27.The creep formulation in this experiment is also derived as follows:HB-2-HB0-2=K exp(- Q/3RT)(t1/3-t01/3)The reasons for the improvement of creep resistance are also discussed from a microstructural point of view. 展开更多
