SiCp/AZ61 matrix composites were fabricated by stirring process in the paper. Different SiC volume fractions, processing temperature and stirring time have different influence on tensile strength and elongation of SiC; it is very difficult to find out the best processing parameters with traditional method. An effective method is demonstrated here: The orthogonal experiment design method is put into use at first, and then a satisfied ANN(Artificial Neural Network) is achieved by help of GA’s(Genetic Algorithm) global optimizing capacity. Experimental results proved the prediction accuracy and the adaptability of our work.

Magnesium matrix composites are prepared with a hybrid optimizing metod here. Different SiC volume fractions, processing temperature and stirring time have different influence on tensile strength and elongation of SiC; but how to find out the satisfied treating parameters is an unavoidable question, a hybrid method is put out and experiments prove the effectiveness of research work.

Mg2Si/AM60 composites were fabricated by in-situ synthesis and the effects of different stirring technological parameters on the microstructures of semi-solid magnesium matrix composites were investigated in this paper. The results indicated that there were Chinese script type Mg2Si particles in the microstructures by addition crystal Si to the magnesium alloys. The mechanical stirring was used to fabricate the semi-solid composites and the results showed that the higher the stirring temperature and speed are, the finer and more homogeneous the spherical grains would be. If the temperature is too high, the grains will be melted. With the increasing of stirring time, the grains become fine, well-distributed and round at first, then grow up.

Aluminum borate whisker (9( Al 2 O 3)·( B 2 O 3)) reinforced AS52(with and without strontium modification) metal matrix composites (MMC) were fabricated by the squeeze infiltration method. Creep rupture test was carried out at 150°C and 100 MPa condition. Results showed that Alborex reinforcement and modified polygonal shape Mg 2 Si phase contributed to the enhancement of mechanical properties and creep resistance. Creep rupture time was increased 11% and minimum creep rate was decreased 17% in the composite. At the Alborex/matrix interface, uniform thin layer of MgO was formed. The initiation of micro-voids at the reinforcement/matrix or Mg 2 Si /matrix interface was followed by their growth and coalescence to macro-cracks.
