COMPOSITE MATERIAL WITH Al-BASE CERAMIC AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite material with Al-base ceramics having a good joint whose void volume is small. SOLUTION: In a joint formed by joining a base material comprising aluminum nitride and a member comprising an Al-base metal to be joined to the base material, a Ge thickened phase and an Mg thickened phase having <=100μm thickness are present along the joining interface.
