抄録

In this study, effect of temperature and Cu contents on Al2O3/Cu composite materials was examined experimentally. Obtained results are sumarized as follow.<br>(1) Microstructure of Al2O3/Cu composite meterial is changed between 50[%] and 75[%] Cu content. That is, amatrix in Al2O3/Cu composite materials with 25[%] and 50[%] Cu content is Al2O3. On the other hand, a matrix in 75[%] Cu content is Cu. (2) Density of the composite materials increases monotonosly with Cu content. Vicker's hardness decreases with Cu content. (3) Coefficient of linear thermal expansion increases with Cu content. (4) Young's modulus decreases with Cu content. (5) Bending strength has strong effect of both of temperature and Cu content.
