Process research of (AlBO)_w/Al composites

To reduce the steps in traditional squeeze casting process of metal matrix composites and decrease costs, the green of aluminum borate whisker was obtained by wet method, and the (AlBO)_w/Al composites were fabricated by liquid-solid squeezing. The process parameters of the whisker green and composites were designed and filtrated through orthogonalization. And the microstructure of (AlBO)_w/Al composites was observed by optional microscope and SEM, etc. The optimum technology parameters of preparing the green and (AlBO)_w/Al composites were obtained. The observation shows that the aluminum borate whisker distributes uniformly in the aluminum alloy matrix. Comparing with the traditional squeeze casting, the process of liquid-solid squeezing cuts down the working operation, thus decreases the cost.
