摘要
采用液态搅融混合半固态挤压成形制备硅线石颗粒增强铝基复合材料，进行了室温和高温机械性能、热膨胀性、摩擦性能试验，结果表明，除σｂ稍下降，δ和αｋ有较大下降外，其它指标（Ｅ，σ０．２和高温性能）均有明显提高，线膨胀系我明显下降，尤其耐磨性提高的幅度更大．这为拓宽硅线石应用领域，进行了有益探索．
The experiment of room and high temperature properties,thermal expansion coeficient tribologicalproperties of aluminium matix panical made with semi-extrusion following blend was studied. The reasult show thatthe ultimate tensile strength ah decrease slightly,the tensile elongation δ and ductility αk decrease greatly; but otherproperties (elastic module E,yield tensile strength σ0.2,mechanical properties in high temperatute),specially the wearresistance of the composite increased remarkably,and coefficient of thermal expansion decrease greatly. There will be anew ways to utilize the sillimanite resource.
