Aging behaviors of alumina borate whisker reinforced AC8A-AI composite
Source abstract
Abstract
The aging behavior of alumina borate whisker (Al18B4O33w/AC8A-Al) composite was examined by hardness and differential scanning calorimetry heat flow measurement. Microstructures were investigated by transmission electronic microscope. The results indicated that the interfacial reaction played an important role in the aging precipitation behavior of the composite. As the interfacial reaction between the whiskers and AC8A-Al alloy consumed the Mg atom of the matrix in the composite, the time to the peak aging of the composite was almost same as that of the AC8A-Al alloy. The free precipitation zone can be found nearby some whisker in the composite, duo to Mg content decreased in the matrix.
