Description

含有成分の量は以下のようにして解析した。電子線マイクロアナライザ（ＥＰＭＡ）（日本電子製ＪＸＡ８１００）を用いて、波長分散型Ｘ線分光法により中間層１１のマトリクス上（析出物以外）の含有成分の量を点分析で１０点以上計測し、その平均値を含有成分の固溶量として計測した。さらに５００倍以上の倍率で４視野以上の視野全体における含有成分の量を含有成分の総量として計測した。さらに、含有成分の固溶量を、含有成分の総量で除算した百分率を、含有成分のうちＡｌと金属間化合物を形成している成分の割合である固溶割合として計測した。そして、固溶割合が、実質的に１００％（例えば９８％以上）である場合に、含有成分の全量が、Ａｌのマトリクス中において固溶体を形成していると見なした。なお、分析時の電子線マイクロアナライザの電子線の加速電圧は１０ｋＶとした。 The amount of the contained component was analyzed as follows. Using an electron beam microanalyzer (EPMA) (JXA8100 manufactured by JEOL Ltd.), the amount of components contained on the matrix of the intermediate layer 11 (other than the precipitate) is measured by point analysis by wavelength dispersion X-ray spectroscopy. The average value was measured as the solid solution amount of the contained components. Furthermore, the amount of the contained component in the entire field of view of 4 or more at a magnification of 500 times or more was measured as the total amount of the contained component. Further, the percentage obtained by dividing the solid solution amount of the contained component by the total amount of the contained component was measured as the solid solution ratio, which is the proportion of the component forming the intermetallic compound with Al. When the solid solution ratio was substantially 100% (for example, 98% or more), it was considered that the total amount of the contained components formed a solid solution in the Al matrix. The acceleration voltage of the electron beam of the electron microanalyzer at the time of analysis was 10 kV.
