grain boundary fractureとは 意味・読み方・使い方

It is possible to provide the silicon nitride-based composite sintered compact having both of high fracture strength and high fracture toughness and suitable for producing structural parts by producing the silicon nitride- based composite sintered compact having grain boundary crystal phases each of which contains, as a main component, ReSiO2N (wherein Re is an element of group 3A of the Periodic Table).例文帳に追加

窒化ケイ素系複合焼結体において、その粒界結晶相をＲｅＳｉＯ__2Ｎ（Ｒｅは周期律表第３Ａ族元素）を主成分とすれば、構造用部品などに好適な高い破壊強度と高い破壊靭性を併せ持つ窒化ケイ素系複合焼結体を提供することができる。 - 特許庁

This polycrystalline silicon is different from general polycrystalline silicon, the covalent binding is not broken in a crystalline grain boundary, the fracture strength is high, and it is suitable for the structure layer.例文帳に追加

この多結晶シリコンは一般的な多結晶シリコンと異なり結晶粒界で共有結合が途切れず破壊応力が高く構造層に好適となる。 - 特許庁

The AIN sintered compact having ≥3.1 MPam^1/2 fracture toughness, ≥420 MPa bending strength, ≥3.1 g/cm^3 density and ≥170 W/mK heat conductivity is obtained by using a specific sintering aid to strengthen the grain boundary and to highly purify the inside of the grain.例文帳に追加

特定の焼結助剤の使用による粒界の強化及び粒内の高純度化により、３．１MPaｍ^1／2以上の破壊靭性と４２０MPa以上の抗折強度を有し、密度が３．１ｇ／cm^３以上、熱伝導率が１７０Ｗ／ｍＫ以上であるAlN焼結体を得る。 - 特許庁
