| Outline of Final Research Achievements |
In order to develop lighter and higher strength Mg composites than the high strength Al alloys, we proposed to laminate Al2O3 / Mg powders with different Al2O3 content, and investigated its light weight and mechanical properties. The 20/0/20 vol% Al2O3 / Mg laminate compacts (laminate compacts) produced had lightness similar to that of a practical Mg alloy. Moreover, they have higher hardness and bending strength than these of 20 vol% Al2O3 / Mg compacts having high mechanical properties. As a result of growing a new phase formed between 20 and 0 vol% layer by long time sintering, the bending strength increased with the increase of the new phase thickness. In the future, in order to obtain specific strength higher than that of high strength Al alloy, we would like to investigate to prepare the laminate compacts having many new phase and the relationship between the microstructure of new phase and the mechanical properties.
