中性子回折は格子面間隔の精密評価に基づいて結晶材料内部の弾性歪みを直接測定できる。無材料除去のままで実際部品の内部組織や変形因子の変化などを非破壊測定的に評価するため、この技術は現代工程材料の設計や古代器物の材料考古学などの分野に特に有効である。本文はISIS核破砕型パルス中性子源に備えたEngin-X中性子回折装置における多数代表性試験研究にめぐって、中性子回折技術は材料科学の深入解明から産業への実際利用まで有効な基礎実験手法であることを示した。

Neutron diffraction methods offer a direct measure of the elastic component of strain deep within crystalline materials through precise characterisation of the interplanar crystal lattice spacing. The unique non-destructive nature of this measurement technique is particularly beneficial in the context of engineering design and archaeological materials science, since it allows the evaluation of a variety of structural and deformational parameters inside real components without material removal, or at worst with minimal interference. We review a wide range of recent experimental studies using the Engin-X materials engineering instrument at the ISIS neutron source and show how the technique provides the basis for developing improved insight into materials of great importance to applications and industry.
