Suitable for modern hightech is widely used, it is characterized in aluminum without damage or less damage while the merits of having the following characteristics: matrix posites, strength and stiffness, high temperature performance is good, more resistant and more resistant to fatigue grinding, good damping properties, low coefficient of thermal expansion. Like other posite materials capable of specific binations of mechanical and physical properties, to meet the needs of the product. Alumina is mainly used A12O3 matrix posites, typically used in aluminum alloys based on aluminum alloys in mon, research alumina particles to increase performance aluminum posite materials are important. In this paper, spiral sample test methods for systems of different temperatures increase the fluidity of the particles of aluminum oxide, by contrast posites spiral specimen length and metallurgical samples at different temperatures to analyze its liquidity. The results showed that: the aluminum alloy volume fraction of 30%, a particle size of Al2O3 particles of the material at 300 ℃ tensile strength still reached 220MPa, and the added alumina particles, but also promote densification, and conductivity of aluminum is not reduced. currently, the alumina particle reinforced aluminum matrix posites, mainly alumina particles may also be added to the NiAlIC221, made between intermetallic matrix posites (IMCS). alumina particles and the matrix has good chemical patibility, almost interfacial chemical reaction does not occur. currently matrix posites reinforced particulate material SiC, AL2O3, BN, etc., intermetallic pounds such as NiAl, FeAl and TiAl also enhanced particles were working.
